Freeze-fracture studies of the developing cell surface. II. Particle-free membrane blisters on glutaraldehyde-fixed corneal fibroblasts are artefacts. (1/723)

We describe, in sections and by freeze-fracture, four classes of intramembrane particle (IMP)-free membrane blebs or "blisters" associated with glutaraldehyde-fixed embryonic corneal fibroblasts: (a) Single blisters attached to the cell membrane; (b) free (detached) vesicles; (c) myelin figures; (d) multivesicular protrusions which resemble the "mounds" described by others on nerve growth cones. The IMP-free, membrane-bounded blisters contain no ground cytoplasm or organelles, in contrast to blebs on trypsin-isolated fibroblasts, which we show here do contain cytoplasm and IMP-rich membranes. That the IMP-free membrane blisters in embryonic corneas are artefacts of fixation is demonstrated by (a) their absence in replicas of fibroblasts frozen and fractured without prior aldehyde fixation and (b) their absence in sections of fibroblasts fixed in a combination of glutaraldehyde and osmium tetroxide. We suggest that the addition of osmium prevents postfixation movement of membrane lipids, especially the negatively charged "fluid" lipids which others have shown are capable of considerable mobility after aldehyde fixation alone. Recent literature has implicated membrane blistering in secretory processes and in growth of nerves, but before the functional significance of such IMP-free blisters is assessed, membrane mobility of the type shown here should be taken into consideration.  (+info)

Nucleoid-independent identification of cell division sites in Escherichia coli. (2/723)

The mechanism used by Escherichia coli to determine the correct site for cell division is unknown. In this report, we have attempted to distinguish between a model in which septal position is determined by the position of the nucleoids and a model in which septal position is predetermined by a mechanism that does not involve nucleoid position. To do this, filaments with extended nucleoid-free regions adjacent to the cell poles were produced by simultaneous inactivation of cell division and DNA replication. The positions of septa that formed within the nucleoid-free zones after division was allowed to resume were then analyzed. The results showed that septa were formed at a uniform distance from cell poles when division was restored, with no relation to the distance from the nearest nucleoid. In some cells, septa were formed directly over nucleoids. These results are inconsistent with models that invoke nucleoid positioning as the mechanism for determining the site of division site formation.  (+info)

A new rapid technique for the fixation of thyroid gland surgical specimens. (3/723)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.  (+info)

Slices have more synapses than perfusion-fixed hippocampus from both young and mature rats. (4/723)

Hippocampal slices have long been used to investigate properties of synaptic transmission and plasticity. Here, for the first time, synapses in slices have been compared quantitatively with synapses occurring in perfusion-fixed hippocampus, which is presumed to represent the natural in vivo state. Relative to perfusion-fixed hippocampus, a remarkable 40-50% increase in spine number occurs in adult hippocampal slices, and a 90% increase occurs in slices from postnatal day 21 rats. Serial EM shows that all of the dendritic spines have normal synapses with presynaptic and postsynaptic elements; however, not all spine types are affected uniformly. Stubby and mushroom spines increase in the adult slices, and thin, mushroom, and branched spines increase in the immature slices. More axonal boutons with multiple synapses occur in the slices, suggesting that the new synapses form on preexisting axonal boutons. The increase in spine and synapse number is evident within a couple of hours after preparing the slices. Once the initial spine induction has occurred, no further change occurs for up to 13 hr in vitro, the longest time investigated. Thus, the spine increase is occurring during a period when there is little or no synaptic activity during the first hour, and the subsequent stabilization in spine synapse numbers is occurring after synaptic activity returns in the slice. These findings suggest that spines form in response to the loss of synaptic activity when slices are removed from the rest of the brain and during the subsequent 1 hr recovery period.  (+info)

Experience with external quality control in spermatology. (5/723)

Results are presented from participation in an external quality control (EQC) programme for semen analysis (UK NEQAS). Formalin-fixed semen samples and videotapes of motile spermatozoa were distributed four times a year over a 3-4 year period. Over the entire period there was close agreement for sperm concentration with, initially, the average of values from the other groups participating in the scheme, and later, values designated as reference values obtained from six laboratories of several chosen that consistently agreed with each other. The initial underestimation of the percentage of normal forms was abolished at the time of change in derivation of designated values and this largely eliminated the difference to establish closer agreement with the designated values. A consistent bias in the assessment of different categories of progressive sperm motility appeared to be resolved by a conscious decision to consider most spermatozoa as grade b and the exceptions as grade a, rather than the converse. Feedback of results to the technicians of the laboratory participating in an external quality control programme leads to reappraisal of subjective evaluation and to harmonization of results between laboratories.  (+info)

Polymerase chain reaction detection of Puumala virus RNA in formaldehyde-fixed biopsy material. (6/723)

BACKGROUND: Infections with hantaviruses, mainly Clethrionomys-derived Puumala viruses, are known causes of acute renal failure [hemorrhagic fever with renal syndrome (HFRS)] in western Europe. Laboratory diagnosis is primarily based on serology. At the time of clinical symptoms, viral RNA can hardly be detected in the blood or urine, indicating that polymerase chain reaction (PCR) is of little diagnostic value for these infections. Biopsy material is usually formaldehyde-fixed and, thus, regarded as poor quality for PCR applications. The aim of this study was to establish a technique to retrieve such material for laboratory diagnostic. METHODS: Formaldehyde-fixed, paraffin-embedded kidney biopsies of 14 patients with renal failure either clinically suspected for HFRS (7 cases) or caused by unknown (2 cases) or known other causes (drugs, sarcoidosis; 5 cases) were histologically investigated. An established S segment-specific PCR assay was applied to RNA isolated from the biopsies, and amplification products were verified by direct sequence determination. RESULTS: Investigations revealed a typical histopathological appearance for hantavirus infections in all seven suspected HFRS cases and one case of unknown cause. With five of the suspected HFRS cases, hantavirus-specific RNA was detected. Sequence comparison revealed a close relationship to corresponding nucleoproteins of known Puumala viruses. CONCLUSION: The established technique provides a simple and powerful tool that expands the diagnostic possibilities, especially for otherwise unidentified or retrospective cases. It further allows insight into the molecular epidemiology of HFRS-causing agents.  (+info)

Detection of translocation t(11;14)(q13;q32) in mantle cell lymphoma by fluorescence in situ hybridization. (7/723)

To assess an unequivocal diagnosis of mantle cell lymphoma (MCL), we have developed a fluorescence in situ hybridization (FISH) assay, enabling the demonstration of t(11;14)(q13;q32) directly on pathological samples. We have first selected CCND1 and IGH probes encompassing the breakpoint regions on both chromosomes. Then, we have defined experimental conditions enabling us to obtain bright clear-cut signals in all of the samples, independently of the initial fixation conditions. We have analyzed single-cell suspensions from 26 formalin-fixed, paraffin-embedded MCL samples with this set of probes. In all cases, we have found a fusion signal (ie, a t(11;14)(q13;q32) translocation) in 14% to 99% of cells (median, 87%). So far, IGH-CCND1 fusions have been detected in all of the 51 MCL patients that we have analyzed by FISH (either on paraffin-embedded tumor samples or on peripheral blood samples). Regarding the low sensitivity of other techniques used to diagnose t(11;14)(q13;q32) (ie, 70% to 75% for cytogenetics and 50% to 60% for polymerase chain reaction), our FISH assay is by far the most sensitive technique. Moreover, because of the quality of the fluorescent signals and the rapidity of the experiment, this technique is widely applicable, even in routine cytogenetics or pathology laboratories. As MCL patients are usually refractory to standard therapy, an unambiguous diagnosis is needed to propose adapted therapeutic strategies, and this highly sensitive assay may be of great value for accurate diagnosis in difficult cases.  (+info)

Mechanical properties of mesenteric arteries in diabetic rats: consequences of outward remodeling. (8/723)

Diabetes induces hemodynamic and biochemical changes that can influence mechanical properties of arteries. Structure and mechanics of mesenteric small arteries were investigated in rats with streptozotocin-induced diabetes (duration 7-9 wk). The external diameter of mesenteric artery branches was measured in control (n = 9) and diabetic (n = 7) Wistar Rp rats at baseline and during pressurization in situ (0-150 mmHg) under normal and passive smooth muscle conditions. Mean arterial pressure and mesenteric artery pressure were not significantly different. Baseline mesenteric artery diameter was larger in the diabetes-induced group (439 +/- 12 vs. 388 +/- 18 micrometers, P < 0.05). Media cross-sectional area of arteries from diabetic rats was not significantly increased (0.0149 +/- 0.0015 vs. 0.0122 +/- 0.0007 mm2). Cross-sectional compliance was significantly increased in diabetic rats at intraluminal pressures ranging from 25 to 75 mmHg (P < 0.005), whereas cross-sectional distensibility was not modified. Wall tension and circumferential wall stress were increased in diabetes. These results indicate that mesenteric small arteries of diabetic rats display eutrophic outward remodeling associated with increased wall tension and circumferential wall stress.  (+info)

The present study was designed to assess the influence of aqueous and nonaqueous fixatives on the quantitative estimation of collagen-proteoglycan interaction in tissue sections. Tissues containing different collagen types and distinct sulfated proteoglycan classes were isolated from pig costal cartilage, human skin, and the inner muscular layer of dog small intestine and fixed using aqueous or nonaqueous methods. the results showed that the best fixation method was exposure to paraformaldehyde gas. When using aqueous fixatives, proteoglycans were lost to different degrees among the various tissues analyzed, reflecting differences in chemical properties of proteoglycan classes and/or in their interactions with other matrix components such as collagen ...

Comparison of histomorphology and DNA preservation produced by fixatives in the veterinary diagnostic laboratory setting [PeerJ]Comparison of histomorphology and DNA preservation produced by fixatives in the veterinary diagnostic laboratory setting [PeerJ]
Histopathology is the most useful tool for diagnosis of a number of diseases, especially cancer. To be effective, histopathology requires that tissues be fixed prior to processing. Formalin is currently the most common histologic fixative, offering many advantages: it is cheap, readily available, and pathologists are routinely trained to examine tissues fixed in formalin. However, formalin fixation substantially degrades tissue DNA, hindering subsequent use in diagnostics and research. We therefore evaluated three alternative fixatives, TissueTek® Xpress® Molecular Fixative, modified methacarn, and PAXgene®, all of which have been proposed as formalin alternatives, to determine their suitability for routine use in a veterinary diagnostic laboratory. This was accomplished by examining the histomorphology of sections produced from fixed tissues as well as the ability to amplify fragments from extracted DNA. Tissues were sampled from two dogs and four cats, fixed for 24-48 h, and processed routinely.

Formaldehyde fixativesFormaldehyde fixatives
The fixative 10% buffered formalin is commonly used to preserve tissues for routine histology in many labs. The formaldehyde has a greater chance for oxidation in this concentration of tissue fixative and eventually the solution will start to drop in pH, in spite of the buffer. We recommend that 10% buffered formalin solutions be used no longer than 3 months after they were initially mixed. The solution should be clear, colorless, with no precipitate and the pH should not be below 6.5.. The other problem with 10% buffered formalin is the slowly increasing concentration of methanol (an unwanted byproduct of aging formaldehyde). Methanol promotes clumping of proteins, instead of the cross-linking of proteins that formaldehyde performs. A methanol-free fixative will give the best preservation, particularly if you plan to use the tissue for antibody staining at a later time.. The most common way to avoid methanol in a formaldehyde solution is to make the solution up fresh from crystalline ...

Overview of Fixation | National DiagnosticsOverview of Fixation | National Diagnostics
To maintain the tissue in as lifelike a state as possible, tissue for analysis is usually placed directly into a fixative solution upon removal from the body. Fixation is normally carried out as soon as possible to prevent autolysis and to reduce possible infectivity. Several factors determine the choice of fixative for a given application. If morphological changes are known to take place rapidly after tissue collection-as with neural tissue-the speed of fixing action is extremely important.. For large tissue samples, the rate of penetration of the fixative into the sample must also be considered. If immunological detection methods are to be used, a fixative which preserves protein structure is required. For electron microscopy, fixatives which do not precipitate proteins avoid artifacts invisible to light microscopy. The price of a fixative may also be a factor. The low cost of formaldehyde fixatives is one reason for their popularity. A partial list of fixatives would include (grouped by ...

In contrast to the Consensus Statement for vasculitis-associated ANCA (23), there are no clear guidelines for immunofluorescence detection and interpretation of ANCA patterns in IBD (24). Differentiating between atypical and typical P-ANCA on ethanol-fixed substrates by IIF is still challenging. Previous data regarding formalin-fixed neutrophils in the detection of atypical P-ANCA are scattered and controversial (4, 7, 31). Differences in formaldehyde fixation techniques and the resolution of the immunofluorescence microscope used might be responsible for these contradictions. However, the use of a formalin-fixed substrate was reported as a simple, useful technique for differentiating between ANA and typical P-ANCA, which may occur together (9). Simultaneous reactivity of atypical P-ANCA on formalin- and ethanol-fixed neutrophils and the feasibility of the new microscopic criteria suggested by Terjung et al. (28) have not been systematically studied in IBD (7, 31). ANCA systems that replace ...

A group of dialdehydes is disclosed having an even number of atoms in the shortest backbone chain connecting the two aldehyde groups which are useful as decontaminants, fixatives, preservatives, and embalming agents. Compared to conventional aldehydes having an odd number of backbone atoms, the even-numbered dialdehydes are approximately as effective in terms of decontaminant, fixative, preservative and embalming properties, yet they are substantially safer to people, animals, and plants, and the environment.

Reagents for Histology: Fixing, Dehydrating, Clearing and StainingReagents for Histology: Fixing, Dehydrating, Clearing and Staining
HISTOCHOICE™ MB® Tissue Fixative is the first fixative designed for the molecular biologist. It is specialty formulated to preserve antigenic sites for antibody probes and nucleic acid sites for immunohistochemistry. HISTOCHOICE™MB® replaces formaldehyde based, alcohol based, Zenkers, B-5, B-3, Bouins and other fixatives with superior results. Tissue fixed in HISTOCHOICE™MB® exhibit vibrant staining, better nuclear and cytoplasmic detail, and will retain a crisp appearance even after long-term fixation.. Because this formula is designed specially for molecular biology applications, HISTOCHOICE™MB® fixed sections do not require pre-digestion or other recovery procedures to make important sites available.This means you spend less time preparing slides and more time doing research.. More than a fixative, HISTOCHOICE™MB® is a preservative that leaves antigens and nucleic acids in their native state, allowing binding for specific probes. Primary antibodies can often be diluted ...

The importance of adequate fixation for immunofluorescent staining of bovine embryosThe importance of adequate fixation for immunofluorescent staining of bovine embryos
article{2019058, abstract = {Immunofluorescent staining is often used to investigate the expression of specific proteins in pre-implantation embryos. The success of this method is determined by the specificity of the antibodies, but also by the protocol used for fixation and permeabilization of the samples. In this study, different fixatives are compared in combination with immunofluorescent staining of caudal-type homeobox 2 (CDX2), fibronectin 1 (FN1) and integrins (ITGs) on bovine blastocysts. For both CDX2 and the ITGs, the outcome of the staining was largely dependent on the fixation methods. Paraformaldehyde fixation was best for the intracellular CDX2 protein, whereas acetone fixation gave the best results for the transmembrane ITGs. No difference was observed for the FN1 staining between samples fixed with paraformaldehyde or acetone. These examples demonstrate that the choice of fixation and permeabilization agents is very important for the outcome of the experiment, and this choice is ...

Glutaraldehyde (Pentanedial) - OpenWetWareGlutaraldehyde (Pentanedial) - OpenWetWare
Glutaraldehyde (1,5-pentanedial, abbreviated as GA) is a common fixative in biology. It is used to reduce degradation in cells, tissues, and entire organisms before further experiments like electron microscopy. Fixation occurs by crosslinking (creating covalent chemical bonds between proteins in/on cells). GA is similar to another common cross-linking fixative, PFA. ...

Detection techniques using antibodies often fail to work on PFA- or formalin-fixed, paraffin-embedded sections. Antigen retrieval methods can then, in some cases, enable specific antibody detection. They work by reversing some of the chemical modification of epitopes during fixation. These procedures will not help much with epitope loss due to denaturation during sample treatment, like hot paraffin embedding. ...

The pH of this solution should be close to pH 7.4, but does not have to be too precise. It is unlikely to produce formalin pigment, unless very bloody tissues are stored in it for a long time without changing the solution, an unlikely situation.. Formal sucrose gives more protection to cytological components and has been recommended as an initial fixative for electron microscopy, if used at 4°C. Otherwise, it is used for phospholipids or whenever greater physical protection is needed for the tissue. It is not usually recommended as a routine formalin fixative as it is basically formalin in a light sugar syrup.. ...

In order to eliminate the labeled free amino acid from the tissue as completely as possible it is advisable to add the corresponding nonradio- active amino acid in excess to the fixative and all solutions subsequently used. For thick emulsion layers 20-30 min of development may be required, depending on the temperature. In some cases it might be necessary to soak the thick emulsion in distilled water prior to development to make it penetrable to the developer.

Effect of Formalin Fixation on Thermal Conductivity of the Biological Tissue | Journal of Biomechanical Engineering | ASME DCEffect of Formalin Fixation on Thermal Conductivity of the Biological Tissue | Journal of Biomechanical Engineering | ASME DC
Effect of formalin fixation on thermal conductivity of the biological tissues is presented. A self-heated thermistor probe was used to measure the tissue thermal conductivity. The thermal conductivity of porcine aorta, fat, heart, and liver was measured before the formalin fixation and then 1 day, 4 days, and 11 days after formalin fixation. The results indicate that the formalin fixation does not cause a significant change in the tissue thermal conductivity of the tissues studied. In the clinical setting, tissues removed surgically are often fixed in formalin for subsequent pathological analysis. These results suggest that, in terms of thermal properties, it is equally appropriate to perform in vitro studies in either fresh tissue or formalin-fixed tissue.. ...

4% NB Formaldehyde - Biognost4% NB Formaldehyde - Biognost
An impeccable sample fixation is a prerequisite for a correct histological diagnosis. Tissue samples must be immersed in an optimally chosen fixative immediately after sampling, because a timely fixation will prevent autolysis, putrefaction and other unwanted cellular changes. Although there are hundreds of histological fixatives and at least tens of formaldehyde-based fixatives, neutral buffered formaldehyde solutions with a concentration range from 4% to 10% are the most commonly used fixatives, primarily because of their simple and universal application. Tissue fixation using a buffered formaldehyde solution results in forming cross-links, i. e. it forms methylene bridges between proteins, that is, it results in keeping tissue components in their in vivo relation. If fixated properly, the tissue sample can withstand additional histological tissue processing and staining.. The NB 4% formaldehyde solution is 10% buffered formalin, which is the most commonly used fixative. It is suitable for ...

Immunocytochemistry. Eleven naive adult male Sprague Dawley rats were anesthetized deeply and perfused transcardially with 10 ml of heparin saline (1000 U/ml), followed by fixative. For 10 rats, the fixative consisted of 50 ml of 3.75% acrolein and 2% paraformaldehyde in 0.1 m phosphate buffer, pH 7.4 (PB), followed by 250 ml of 2% paraformaldehyde. To determine whether the degree of DAT immunostaining was dependent on the fixative that was used, we perfused the remaining animal with 500 ml of 4% paraformaldehyde with 0.2% glutaraldehyde. The brains were removed, post-fixed in the final fixative for 30 min, and sectioned at 50 μm on a vibratome. To improve antigenicity and reduce nonspecific immunolabeling, we subsequently treated the sections for 30 min with 1% sodium borohydride (Leranth and Pickel, 1989) and rinsed them in PB. To reduce further the nonspecific labeling before incubation in primary antibody, we treated sections for 30 min in a blocking solution consisting of 1% bovine serum ...

Practical aspects of glutaraldehyde fixation. Five important points must be remembered when using glutaraldehyde as a fixative for light or electron microscopy.. 1. If its to be any use as a fixative, especially for electron microscopy, the glutaraldehyde solution must contain the monomer and low polymers (oligomers) with molecules small enough to penetrate the tissue fairly quickly. This means you must buy an « EM grade » glutaraldehyde (25% or 50% solution), not a cheaper « technical » grade. The cheaper stuff, which is for tanning leather, consists largely of polymer molecules too large to fit between the macromolecules of cells and other tissue components.. 2. The chemical reaction of glutaraldehyde with protein is fast (minutes to hours), but the larger molecules, especially the oligomers, penetrate tissue slowly. A rats brain left overnight in a buffered glutaraldehyde solution and sliced the next day shows a colour change and harder consistency to a depth of 2-3 mm. Objects fixed ...

Comparison of Methods for the Extraction of DNA from Formalin-Fixed, Paraffin-Embedded Archival TissuesComparison of Methods for the Extraction of DNA from Formalin-Fixed, Paraffin-Embedded Archival Tissues
Since 1984, several human tissue banks have been available to researchers in the field of molecular biology in the USA [9-11]. The goal of these procurement organizations is primarily to provide tissues to researchers seeking to screen for genetically based diseases and the genetic bases of diseases. Nevertheless, multiple factors affect the molecular profiles of cells. These factors that affect these profiles in FFPE tissues include pre-fixation time, the properties of the fixatives, the conditions of the fixative, and the post-fixative storage parameters. The main goal is to preserve nucleic acids in diagnostic specimens for the identification of specific diagnostic and prognostic molecular targets [12].. In biomedical science, the human tissues that researchers receive are nearly always tissues that remain after routine diagnostic procedures. Worldwide, the most commonly used fixative agent for these tissues is formalin (HCHO). Formalin is an agent that forms crosslinks between the lysine ...

College of American Pathologists - Fixing FFPE specimens for genomic ageCollege of American Pathologists - Fixing FFPE specimens for genomic age
In summary, doing QC of RNA profiles requires a new approach. When testing so many things at once, it requires a new paradigm for doing QC, Dr. Gulley says. You cant possibly have negative and positive controls for every analyte in a large panel. So what we are controlling instead is the overall process of classifying the sample into one of the important categories of outcomes, such as a molecular subtype of breast cancer.. In her interview with CAP TODAY, Dr. Nikiforova, too, had thoughts on improving the quality of assays on RNA and DNA from FFPE tissue. She agrees that tissue should not be fixed in formalin for too long, certainly not for more than 48 hours. In addition, fixatives other than formalin might make nucleic acids inaccessible for extraction. In this regard, she cites the heavy metal fixative B5. Another typical error: sending tissue that was in the process of decalcification. Decalcification solutions cause extensive DNA fragmentation, she says.. In her laboratory, Dr. ...

Intracellular fills of astrocytes with fluorescent dyes in fixed tissue. The method for filling cells in fixed tissue slices was adapted from previously reported protocols (Buhl, 1993; Belichenko and Dahlström, 1995). Male Sprague Dawley rats, 1 month of age, were anesthetized with an overdose of Nembutal (10 mg/100 gm body weight) and perfused transcardially with oxygenated Ringers solution at 37°C (0.79% NaCl, 0.038% KCl, 0.020% MgCl2·6H2O, 0.018% Na2HPO4, 0.125% NaHCO3, 0.030% CaCl2·2H2O, 0.20% dextrose, and 0.020% xylocaine) for ∼30 sec, followed by 0.1m PBS, pH 7.4, containing 4% paraformaldehyde (37°C). For electron microscopic studies, 0.1% glutaraldehyde was added to the fixative. The fixative was perfused through the body for 10 min, at which point the brain was removed and cut on a vibratome into 100-μm-thick coronal slices. The slices were stored in ice-cold PBS and used within 48 hr. The slices were placed in cold PBS and viewed with an Olympus Optical (Melville, NY) BX50WI ...

Different methods of fixation and tissue processing were employed to demonstrate intracellular antibody to horseradish peroxidase, Escherichia coli alkaline phosphatase and glucose oxidase in lymph node of several species. Fixation with various glutaraldehyde and formaldehyde fixation procedures were tried. None of those fixatives appeared to inhibit the subsequent antigen-antibody reaction. Small fragments of lymph node were cut either by hand with a razor blade or by using a tissue chopper and complete cross sections of the node were cut at 40 µm thickness in a cryostat. The latter method gave the most consistently reproducible results in that antibodies to all 3 enzymes were demonstrable: The intracellular penetration of the enzymes was superior with this method, and specific areas in the lymph node could be selected by light microscopy prior to cutting thin sections. Finally, a technique is described whereby antibody antihorseradish peroxidase can be detected in ultrathin frozen sections ...

Exaltolide - Pell WallExaltolide - Pell Wall
Very fine and elegant musk with a natural quality, adds depth and roundness to a wide variety of creations but it also has a synergistic effect on the bouquet of a fragrance. At ,98% purity this generic is the equivalent of the Firmenich product Exaltolide (as distinct from Exaltolide Total, which is at 92% purity) although not manufactured by Firmenich.. Arctander describes it like this: Delicately animal, musky and sweet, extremely tenacious odor of outstanding uniformity. Its fixative effect is absolutely unusual in that it is not a physical fixation, but a true fixative and mellowing effect at incredibly low concentration of usage. The effect of perfumes containing this Lactone differ from others in the excellent wearability introduced by the Lactone. This is particularly conspicuous when the perfume is applied to the skin. According to Philip Kraft, Exaltolide is probably the commercial musk with the least side notes. He therefore recommends using it as a benchmark for grasping the ...

Tracing Cell Proliferation by Generation after Generation | ABP BiosciencesTracing Cell Proliferation by Generation after Generation | ABP Biosciences
Tracing cell division using a fluorescent label allows scientists to detect and quantify cell proliferation through multiple generations (Figure 1). Our Cell-ID™ Cell Proliferation Kits (Table 1) contain specially designed fluorescent labels, which can easily cross the plasma membrane and covalently label with protein inside cells without affecting morphology or physiology. During cell division, the fluorescent label is divided evenly between two daughter cells. Based on the fluorescence intensity, the proliferating cells can be easily detected up to 6 to 10 generations, even after several days in a cell culture environment or following fixation (Figure 2 ...

Caveat: These tests are not as exacting as are chemical, analytical tests. All persons involved ought to be properly trained and competent for interpretation. The lab should be officially accredited and involved in an official external competency survey program. The individual test should be quality controlled with a slide containing tissue elements with known positive (graded positives...weak/medium/strong...if possible) and negative control reactions to assure that the test system and reagents all worked properly. It is further optimal if the pathologist selects a tissue block for testing which will include some normal patient tissues which should react positively...positive internal auto-control (to assure that the test tissue was properly handled and processed and is capable of positive reactions). Prompt fixation (NBF is considered universally OK with at least 6 hours exposure in fixative & not much more than 48 hours) is vital. Not only should a positive reaction make sense with the ...

A different clue to the system of Girdin-mediated mobile migration GSK137647A chemical informationand polarization is that cell porality proteins such as Par-three were recognized by a genome-vast display screen as regulators for the endocytic trafficking pathway [61]. Thinking about the localization of Girdin molecules on the network of actin filaments just beneath the plasma membrane [seven], cell-mobile get hold of websites in neuroblasts [9], and intracellular vesicles [16], it is plausible to speculate that Girdin cooperates with Par-3 to regulate endocytosis at the foremost edge or postfixed in the same fixative overnight, reduce into sections on a microslicer (VT1200S, Leica) and immunolabeled for fluorescence microscopy. For immunofluorescence reports, sections have been incubated with anti-c-tubulin and Dcx antibodies diluted in PBS and used to sections overnight at 4uC.
