Human serum albumin (HSA) is a mixture of human mercaptalbumin (HMA, reduced form) and nonmercaptalbumin (HNA, oxidized form). We have developed a convenient high-performance liquid chromatographic (HPLC) system for the separation of HSA into HMA and HNA, and studied the mercapt,==,nonmercapt conversion (i.e., dynamic change in the redox state) of HSA. Examination of long-term sample preservation temperature on the redox state of HSA is of fundamental importance for analysis of defense systems against oxidants in humans. The HMA fraction of HSA (f(HMA)) was markedly decreased, i.e., the redox state of HSA samples was more oxidized, when they were kept even at -20 degrees C for 170 days. Moreover, the redox states of five commercial HSA products were analyzed and the results were compared with those for normal control subjects. Surprisingly, marked decreases in f(HMA) value for all commercial HSA products were observed. ...

Many archaeological bones display a heterogeneous degradation pattern. Highly degraded bones could contain pockets of well-preserved bone, harbouring good quality DNA. This dichotomy may explain why the relationships between global bone preservation parameters such as histological integrity, bone mineral crystallinity or collagen yield, and bulk DNA preservation/amplification success rate have been found to be at best, weak to moderate. In this pilot study, we explore whether or not a more localised approach will highlight a stronger relationship between diagenetic parameters and DNA preservation. This study includes a detailed histological characterisation of bone diagenesis in sub-areas of three bone samples. Regions of the same bone, which displayed differential degrees of preservation or type of diagenesis were sampled for further analysis and both genetic (small scale Illumina MiSeq sequencing) and chemical (Fourier-transform infrared spectrometric analysis) analyses were performed. The aim ...

The effect of cryopreservation and long-term liquid nitrogen storage on peripheral blood mononuclear cell (PBMC) subsets was prospectively analyzed using monoclonal antibodies and flow cytometry.

Background Non-invasively collected samples allow a variety of genetic studies on endangered and elusive species. However due to low amplification success and high genotyping error rates fewer samples can be identified up to the individual level. Number of PCRs needed to obtain reliable genotypes also noticeably increase. Methods We developed a quantitative PCR assay to measure and grade amplifiable nuclear DNA in feline faecal extracts. We determined DNA degradation in experimentally aged faecal samples and tested a suite of pre-PCR protocols to considerably improve DNA retrieval. Results Average DNA concentrations of Grade I, II and III extracts were 982pg/µl, 9.5pg/µl and 0.4pg/µl respectively. Nearly 10% of extracts had no amplifiable DNA. Microsatellite PCR success and allelic dropout rates were 92% and 1.5% in Grade I, 79% and 5% in Grade II, and 54% and 16% in Grade III respectively. Our results on experimentally aged faecal samples showed that ageing has a significant effect on quantity

Validity of biobank studies on hormone associated cancers depend on the extent the sample preservation is affecting the hormone measurements. We investigated the effect of long-term storage (up to 22 years) on immunoassay measurements of three groups of hormones and associated proteins: sex-steroids [estradiol, progesterone, testosterone, dihydroepiandrosterone sulphate (DHEAS), sex hormone-binding globulin (SHBG)], pregnancy-specific hormones [human chorionic gonadotropin (hCG), placental growth hormone (pGH), alpha-fetoprotein (AFP)], and insulin-like growth factor (IGF) family hormones exploiting the world largest serum bank, the Finnish Maternity Cohort (FMC). Hormones of interest were analyzed in a random sample of 154 Finnish women in the median age (29.5 years, range 25 to 34 years) of their first pregnancy with serum samples drawn during the first trimester. All hormone measurements were performed using commercial enzyme-linked- or radio-immunoassays. Storage time did not correlate with ...

The formulation of novel therapeutic proteins is a challenging task which aims at finding formulation conditions that will minimize protein degradation during long-term storage. One particularly important and difficult-to-predict protein degradation pathway is the so-called non-native aggregation. The qualitative and quantitative prediction of the latter has been a subject of extensive research over the past two decades. An increasing body of evidence shows that the widely-used short-term biophysical techniques cannot accurately rank formulation conditions in order of their effect on the aggregation during long-term storage of some therapeutic proteins, e.g. monoclonal antibodies. Here we suggest a novel approach for the selection of formulation conditions that will suppress the formation of protein aggregates during long-term storage. We postulate that conditions (i.e. pH, buffer type, ionic strength) that reduce the isothermal aggregation of various denaturant-induced partially folded protein ...

N2 - Background: Primary human tissues are an invaluable widely used tool for discovery of gene expression patterns which characterize disease states. Tissue processing methods remain unstandardized, leading to unanswered concerns of how to best store collected tissues and maintain reproducibility between laboratories. We subdivided uterine myometrial tissue specimens and stored split aliquots using the most common tissue processing methods (fresh, frozen, RNALater) before comparing quantitative RNA expression profiles on the Affymetrix U133 human expression array. Split samples and inclusion of duplicates within each processing group allowed us to undertake a formal genome-wide analysis ...

Understanding the advantages and suitability of different methods to measure residual moisture content in lyophilized materials-and the respective limitations-aids in selecting the most appropriate method for testing.

The use of energy crops and agricultural residues is expected to increase to fulfil the legislative demands of bio-based components in transport fuels. Ensiling methods, adapted from the feed sector, are suitable storage methods to preserve fresh crops throughout the year for, for example, biogas production. Various preservation methods, namely ensiling with and without acid addition for whole crop maize, fibre hemp and faba bean were investigated. For the drier fibre hemp, alkaline urea treatment was studied as well. These treatments were also explored as mild pretreatment methods to improve the disassembly and hydrolysis of these lignocellulosic substrates. The investigated storage treatments increased the availability of the substrates for biogas production from hemp and in most cases from whole maize but not from faba bean. Ensiling of hemp, without or with addition of formic acid, increased methane production by more than 50% compared to fresh hemp. Ensiling resulted in substantially increased

Eppendorf ULT Freezers such as the CryoCube FC660 are known for their energy efficiency, reliability, and worry-free, long-term sample preservation.

PI: Jim Smith, University of Portsmouth.. The formation of cataract in humans due to occupational or accidental exposure to acute ionising radiation is well documented. However, little is known about the effect of long-term chronic exposure through the life span of organisms exposed in the natural environment. A recent study of voles at Chernobyl (Lehmann et al. Scientific Reports 6; 2016), apparently found significant increases in cataract incidence at cumulative doses as low as 10 mSv. This generated significant media coverage and, if true, would represent a major challenge to current radiation protection regulation. Key flaws in this study, however, were the method of field sample preservation/preparation, and the subjective nature of the lens opacity measurement.. The purpose of the proposed study is to further develop methods for stabilisation and preparation of fish lens samples to measure any ultrastructural changes to the constituent crystallin proteins within the lens fibre cells caused ...

Currently, two main types of amniotic membrane (AM) are commercially available for in-office use: cryopreserved and dehydrated. Both types come in a variety of tissue thicknesses and sizes, depending on clinical needs.. Cryopreserved AM. Cryopreservation of AM involves slow freezing at -80°C using DMEM/glycerol preservation media to allow for slow-rate freezing without ice formation. This preservation technique retains the extracellular matrix components, such as heavy-chain hyaluronic acids, growth factors, fibronectin, and collagen, all of which promote anti-inflammatory effects and healing. The tissue is stored in a -80°C freezer and brought to room temperature when needed for use.. ProKera (BioTissue) is a cryopreserved form of AM in which the membrane is secured around a polycarbonate ring or an elastomeric band. It requires no assembly and is inserted into the eye in a manner similar to contact lens placement. This form of AM has been cleared by the FDA as a class II medical device, and ...

NOTE: The use of DMSO may not be appropriate for all cell lines (e.g. where DMSO is used to induce differentiation). In such cases an alternative such as glycerol should be used.. Following controlled-rate freezing (see above) in the presence of cryoprotectants, cell lines can be cryopreserved in a suspended state for indefinite periods provided a temperature of less than -165°C is maintained. TCCF uses ultra-low temperatures, attained by use of specialized containers (usually by immersion in liquid or vapor-phase nitrogen). The advantages and disadvantages can be discussed with the TCCF director.. Our liquid nitrogen storage vessels are equipped with alarms system. TCCF personnel ensure liquid nitrogen delivery in a timely fashion. It is highly recommended that valuable cell stocks should be backed up by storage at a second site.. ...

Saliva contains components of both the mucosal and systemic immune systems. Variable flow rates, immunoglobulin proteases, and variation in collection and storage methods all introduce differences in the estimated concentrations of antibodies. We evaluated the effect of four collection methods and three storage protocols on the concentrations of immunoglobulin A (IgA) antibodies to pneumococcal capsular antigens 1, 5, 6B, and 14 and to pneumococcal surface adhesin A (PsaA) in saliva. Specimens were collected from 30 healthy Kenyan adults by collecting drool, by pipette suction, and with two commercial kits, OraSure and Oracol. Aliquots from each specimen were snap-frozen with glycerol in liquid nitrogen or stored for 4 to 8 h at +4 degrees C either with or without the addition of protease enzyme inhibitors prior to storage at -70 degrees C. Anticapsular IgA concentrations were not significantly different with different collection methods, but snap-freezing the specimens in liquid nitrogen led to
