Freeze-fracture studies of the developing cell surface. II. Particle-free membrane blisters on glutaraldehyde-fixed corneal fibroblasts are artefacts. (1/776)

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)

Role of glutaraldehyde in calcification of porcine aortic valve fibroblasts. (2/776)

Glutaraldehyde-treated porcine aortic valve xenografts frequently fail due to calcification. Calcification in the prostheses begins intracellularly. In a previous study, various types of cell injury to canine valvular fibroblasts, including glutaraldehyde treatment, led to calcification. An influx of extracellular Ca2+ into the phosphate-rich cytosol was theorized to be the mechanism of calcification. To test the Ca2+ influx theory, cytosolic Ca2+ and Pi concentrations were assessed in glutaraldehyde-treated porcine aortic valve fibroblasts, and their relationship to a subsequent calcification was studied. Glutaraldehyde caused an immediate and sustained massive cytosolic Ca2+ increase that was dose dependent and a several-fold increase in Pi. Calcification of cells followed within a week. The earliest calcification was observed in blebs formed on glutaraldehyde-treated cells. Live control cells or cells fixed with glutaraldehyde in Ca2+-free solution did not calcify under the same conditions. Concomitant increases in Ca2+ and Pi in glutaraldehyde-treated cells appear to underlie the mechanism of calcification, and the presence of extracellular Ca2+ during glutaraldehyde fixation promotes calcification.  (+info)

Mitochondrial telomere-binding protein from Candida parapsilosis suggests an evolutionary adaptation of a nonspecific single-stranded DNA-binding protein. (3/776)

The mitochondrial genome in a number of organisms is represented by linear DNA molecules with defined terminal structures. The telomeres of linear mitochondrial DNA (mtDNA) of yeast Candida parapsilosis consist of tandem arrays of large repetitive units possessing single-stranded 5' extension of about 110 nucleotides. Recently we identified the first mitochondrial telomere-binding protein (mtTBP) that specifically binds a sequence derived from the extreme end of C. parapsilosis linear mtDNA and protects it from attack by various DNA-modifying enzymes (Tomaska, L'., Nosek, J., and Fukuhara, H. (1997) J. Biol. Chem. 272, 3049-3059). Here we report the isolation of MTP1, the gene encoding mtTBP of C. parapsilosis. Sequence analysis revealed that mtTBP shares homology with several bacterial and mitochondrial single-stranded DNA-binding proteins that nonspecifically bind to single-stranded DNA with high affinity. Recombinant mtTBP displays a preference for the telomeric 5' overhang of C. parapsilosis mtDNA. The heterologous expression of a mtTBP-GFP fusion protein resulted in its localization to the mitochondria but was unable to functionally substitute for the loss of the S. cerevisiae homologue Rimlp. Analysis of the MTP1 gene and its translation product mtTBP may provide an insight into the evolutionary origin of linear mitochondrial genomes and the role it plays in their replication and maintenance.  (+info)

Ligand binding properties of the very low density lipoprotein receptor. Absence of the third complement-type repeat encoded by exon 4 is associated with reduced binding of Mr 40,000 receptor-associated protein. (4/776)

The very low density lipoprotein receptor (VLDLR) binds, among other ligands, the Mr 40,000 receptor-associated protein (RAP) and a variety of serine proteinase-serpin complexes, including complexes of the proteinase urokinase-type plasminogen activator (uPA) with the serpins plasminogen activator inhibitor-1 (PAI-1) and protease nexin-1 (PN-1). We have analyzed the binding of RAP, uPA.PAI-1, and uPA.PN-1 to two naturally occurring VLDLR variants, VLDLR-I, containing all eight complement-type repeats, and VLDLR-III, lacking the third complement-type repeat, encoded by exon 4. VLDLR-III displayed approximately 4-fold lower binding of RAP than VLDLR-I and approximately 10-fold lower binding of the most C-terminal one of the three domains of RAP. In contrast, the binding of uPA.PAI-1 and uPA.PN-1 to the two VLDLR variants was indistinguishable. Surprisingly, uPA.PN-1, but not uPA.PAI-1, competed RAP binding to both VLDLR variants. These observations show that the third complement-type repeat plays a crucial role in maintaining the contact sites needed for optimal recognition of RAP, but does not affect the proteinase-serpin complex contact sites, and that two ligands can show full cross-competition without sharing the same contacts with the receptor. These results elucidate the mechanisms of molecular recognition of ligands by receptors of the low density lipoprotein receptor family.  (+info)

Functional domain structure of human heterochromatin protein HP1(Hsalpha): involvement of internal DNA-binding and C-terminal self-association domains in the formation of discrete dots in interphase nuclei. (5/776)

Human heterochromatin protein HP1(Hsalpha) possesses two evolutionarily conserved regions in the N- and C-terminal halves, so-called chromo and chromo-shadow domains, and DNA-binding domain in the internal non-conserved region. Here, to examine its in vivo properties, we expressed HP1(Hsalpha) as a fusion product with green fluorescent protein in human cells. HP1(Hsalpha) was observed to form discrete dots in interphase nuclei and to localize in the centromeric region of metaphase chromosomes by fluorescence microscopy. Interestingly, this dot-forming activity was also found in the N-terminal half retaining the chromo and DNA-binding domains and in the C-terminal chromo-shadow domain. However, the chromo domain alone stained nuclei homogeneously. To correlate this dot-forming activity with self-associating activity in vitro, the chromo and chromo-shadow domain peptides were independently expressed in Escherichia coli, affinity purified, and chemically cross-linked with glutaraldehyde. In a SDS-polyacrylamide gel, the former mainly produced a dimer, while the latter produced a ladder of bands up to a tetramer. When passed through a gel filtration column in a native state, these peptides were exclusively separated as a dimer and a tetramer, respectively. These results suggested that the internal DNA-binding and C-terminal chromo-shadow domains are both involved in heterochromatin formation in vivo.  (+info)

Disinfection of upper gastrointestinal fibreoptic endoscopy equipment: an evaluation of a cetrimide chlorhexidine solution and glutaraldehyde. (6/776)

There is little information available on the bacteriological contamination of upper gastrointestinal fibreoptic endoscopes during routine use and the effects of 'disinfecting solutions'. A bacteriological evaluation was therefore made of cleaning an endoscope and its ancillary equipment with (1) water, (2) an aqueous solution of 1% cetrimide with 0.1% chlorhexidine, and (3) activated aqueous 2% glutaraldehyde. All equipment, but particularly the endoscope itself, was found to be heavily contaminated after use with a wide variety of organisms of which 53% were Gram positive. Cleaning the endoscope and ancillary equipment with water and the cetrimide/chlorhexidine solution alone or in combination was inadequate to produce disinfection but immersion in glutaraldehyde for two minutes consistently produced sterile cultures with our sampling technique. A rapid and simple method for disinfection of endoscopic equipment is therefore recommended and we think this is especially suitable for busy endoscopy units.  (+info)

Antigenicity of purified glutaraldehyde-treated cholera toxoid administered orally. (7/776)

The antigenicity of orally administered glutaraldehyde-treated cholera toxoid was investigated in healthy volunteers. Fourteen volunteers ingested two or three 2-mg doses of toxoid with saline, with the doses spaced at 28-day intervals. Thirteen other volunteers received comparable toxoid doses with NaHCO3 and milk to neutralize gastric acid. Increments in circulating antitoxin levels were used to assay the antigenicity of oral toxoid. Antitoxin was measured by adrenal cell, rabbit skin permeability factor, and passive hemagglutination assays in sera collected on days 0, 28, 35, 56, 63, and 84 after primary immunization. Adrenal cell and rabbit skin assays exhibited identical sensitivity in detecting antitoxin rises in the 27 vaccinees (19/27) and were significantly more sensitive than passive hemagglutination (11/27) (P less than 0.03). Volunteers who ingested toxoid with NaHCO3 and milk had a higher rate of seroconversion (77%) than those who received toxoid with saline (64%); they also had earlier rises in antitoxin titer and consistently higher geometric mean titers on all days tested. These studies demonstrate that purified cholera toxoid is antigenic in humans after oral administration. The possible role of oral toxoid in enhancing the protective effect of killed whole-cell vaccines can now be investigated.  (+info)

Slices have more synapses than perfusion-fixed hippocampus from both young and mature rats. (8/776)

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)

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 ...
Lack of information regarding the presence of native albumin polymer in serum and its structural similarity to the one produced by glutaraldehyde treatment casts doubt on the postulate that hepatitis B virus attachment to hepatocytes is mediated through polymerized albumin. We used a sandwich enzyme-linked immunosorbent assay with murine monoclonal antibodies raised against glutaraldehyde-polymerized albumin to detect native albumin polymer in human serum and its cross-reactivity with other albumin polymers. Presence of polymerized albumin receptor on the HepG2 cell was studied by radioreceptor assay. Purified hepatitis B virus and synthetic peptide analogous to part of pre-S2 sequence (120-145) were used to study polymerized albumin-dependent attachment of the virus to HepG2 cells. Antibodies raised against pre-S2 peptide were used to inhibit the pre-S2 and hepatitis B virus attachment to HepG2 cells. Glutaraldehyde-treated polymerized albumin was found to be immunologically cross-reactive with ...

The minute I stepped into the physicians practice, I could smell the glutaraldehyde solution. This mixture should ALWAYS be kept in a tightly closed container.
Glutaraldehyde chemistry has been used to immobilize lipase B from Candida antarctica (CALB) under different situations. Using high ionic strength, ionic adsorption is avoided, but CALB is adsorbed on the support via interfacial activation. Using non-ionic detergents (e.g., Triton X-100), the enzyme becomes ionically adsorbed on the activated support. If detergent and salt are simultaneously present during immobilization, a covalent attachment to the support is first produced. In absence of detergent or high ionic strength, a mixture of all of the previous immobilization reasons should coexist. Thus, 5 different CALB biocatalysts were prepared following the previous described protocols, and its stability and activity, pH/activity profile and specificity versus R and S methyl mandelate were analyzed. The existence of covalent attachment of more than 95% of the enzyme molecules was confirmed by washing the biocatalysts in salt and detergent solutions. The glutaraldehyde treatment of the enzyme ...
The identification of protein tyrosine kinases (PTKs) was successfully achieved by renaturation in gels after SDS/PAGE. To this effect, samples were mixed with a PTK substrate, namely the polydispersed co-polymer of glutamic acid and tyrosine [poly(Glu, Tyr), M(r) from 30,000 to 94,000], and were simultaneously submitted to electrophoresis. Following guanidine hydrochloride denaturation, renaturation and phosphorylation with [gamma-32P]ATP, kinase activity was detected by autoradiography. When applied to cytosol from human hyperplastic prostate, eleven protein kinases were detected, among which one major (M(r) 50,000) and two minor proteins (M(r) 40,000 and 38,000) were identified as PTKs by the presence of phosphotyrosine. Incubation of the gel in hot alkali after glutaraldehyde cross-linking almost completely eliminated the detection of non-PTK enzymes. On the other hand, in the absence of poly(Glu,Tyr), no PTK activity was detected. Partial purification of cytosolic PTKs indicates that the native M(r

No significant change was found in the electrolytes and lipids of the brain analyzed after glutaraldehyde fixation by perfusion of laboratory animals; such fixation also satisfactorily preserves neural tissues for electron microscopy. The brains of normal and tumor-bearing C3H mice, Wistar rats, and New Zealand rabbits were studied. Little difference was found in the dry weight and the content of sodium, potassium, total lipid and lipid fractions, and in the sulfate space (S35O4) between specimens from unperfused and perfused animals, whether normal or tumor-bearing. The results suggest the possibility of using selected regions of the nervous system, dissected after fixation, for chemical study and at the same time characterizing similar regions morphologically with the electron microscope. ...

Staining and clearing both will require chemicals to diffuse in to the sample which requires the removal or breaking (in some way) of any barriers to permeabillity for the chemicals you are using. This will often be combined with long times, gentle agitation, and some preservation method depending on how the tissue is treated (such as fixed or not fixed). Fixation chemically modifies molecules found in the tissue, making them immobile. For example gluteraldehyde cross links proteins which prevents them from moving, but also making the spaces for staining molecules to pass through smaller ...

Using a Polaron E7200 quick freeze unit, we investigated the distribution of vesicles (caveolae) bound to the plasma membrane of aortic endothelial cells from adult Sprague-Dawley rats. Counts of caveolae from replicas of rapidly frozen, unfixed samples were made and compared with counts from both aldehyde-fixed, conventionally frozen, and rapidly frozen aortic samples. Aldehyde-fixed samples prepared for freeze fracture by either of the freezing methods revealed a significantly greater number of caveolae than did unfixed, rapidly frozen samples. These findings suggest that the relative number of caveolae is artifactually increased by exposure to aldehyde fixatives. We conclude that previous estimates of the rates of pinocytotic activity in vascular endothelial cells may contain substantial errors based on overestimates of caveolae and underestimates of subplasmalemmal free vesicles. ...
Utilization of reproducible and degradable biomass, particularly that from inexpensive, abundant, and sustainable resources opens an effective way to create high-value carbon materials. Here, we explore for the first time, the direct synthesis of porous carbon fibers from collagen derived from chicken feet in a sustainable method. Chicken feet can provide an abundant supply of young (normally , 42 days old)collagenous tissue which can readily be converted to a purified collagen solution. We have demonstrated a new process using a simple and scalable fiber production technology for the production of large fiber quantities. Porous carbon fibers with diameters range from 30 to 50 μm were formed via wet spinning of collagen materials derived from chicken feet. Glutaraldehyde cross-linked as well as untreated collagen fibers were spun in a buffer coagulation bath without compromising flexibility. The present study provides an affordable solution to a growing agricultural waste disposal and health ...

It is unknown how fluorescein suffuses into the TM from SC. However, the naturally existing pores and the canaloplasty-created ruptures of the inner wall of SC might be involved. The endothelial cells of the inner wall have a total of approximately 20,000 pores with diameters of up to 3 μm. 35 These pores with adjacent JCT may cause a funneling effect in which aqueous humor from the AC flows preferentially through those regions of the JCT near the pores and then enters SC through the pores. 36 This hydrodynamic interaction between the inner wall endothelium and the JCT may lead to a resistance that is larger than the resistance these tissues would generate individually without their proximity to one another. 37 However, when the injected vector solution flows from SC to the TM under a reversed pressure gradient, the transgene particles could directly cross all pores and enter the JCT. Retroperfusion (fluid flowing from the limbus/SC to the TM) with glutaraldehyde at zero or negative IOP in ...

Using the former fixation method, fibronectin immunoreactivity was detected (1) at the ventral surface of the upper layer or epiblast, mainly anterior and lateral to Hensens node, in regions where middle-layer or mesoblast cells are not yet present, and (2) sparsely in extracellular spaces of the deep layer. Using the latter fixation method, fibronectin immunoreactivity was, moreover, found ...

Generation of fz3(−/−) mice. The fz3knock-in construct (see Fig. 1) was electroporated into R1 cells, and colonies were grown in medium containing G418 and gancyclovir. Colonies were picked 8 d after plating and screened by Southern blot hybridization. Positive embryonic stem cell clones were injected into C57BL/6 blastocysts.. Histochemistry. Throughout this study, the first day after overnight mating is counted as embryonic day 0 (E0). Tissues for 5-bromo-4-chloro-3-indolyl-β-d-galactopyranoside (X-gal), NADPH diaphorase, and acetylcholine esterase staining were immersion fixed 2-6 hr at 4°C in PBS, 2.5% formalin, and 0.2% gluteraldehyde; embedded in 3% agarose in PBS; and sectioned at 300 μm on a vibratome. Embryos younger than embryonic day E15 were fixed intact; for later stage embryos, fixation proceeded with isolated heads from which the skin had been removed. Before cutting vibratome sections, later stage heads were incubated at 4°C for 5-7 d in 0.5× PBS, 20 mm Na EDTA to ...
