aflatoxins are a group of fungal toxic metabolites, which are contaminated certain food commodities. elisa is one of the sensitive methods for detection of aflatoxins. preparation and stabilizing of a proper conjugated tracer for detection of aflatoxins is probably the main step for designing an elisa method. in current study, different stabilizers were applied to stabilize a newly prepared con...

This study was undertaken to determine whether and how advanced glycation end products (AGE), senescent macroproteins accumulated in various tissues under hyperglycemic states, cause angiogenesis, the principal vascular derangement in diabetic microangiopathy. We first prepared AGE-bovine serum albumin (BSA) and anti-AGE antiserum using AGE-RNase A. Then AGE-BSA was administered to human skin m...

Interactions between proteins and drugs, which can lead to formation of stable drug-protein complexes, have important implications on several processes related to human health. These interactions can affect, for instance, free concentration, biological activity, and metabolism of the drugs in the blood stream. Here, we report on the UV-Visible spectroscopic investigation on the interaction of b...

We reported previously that yeast-derived whole glucan particles (WGPs), with or without conjugation to BSA, used as a vaccine protected against systemic aspergillosis in mice. Here, we examined their utility as a potential vaccine against coccidioidomycosis. WGPs were prepared from Saccharomyces cerevisiae; conjugation with BSA (WGP-BSA) was done using 1-cyano-4-dimethylaminopyridinium tetrafl...

The full potential of diagnostic PCR is limited, in part, by the presence of inhibitors in complex biological samples that reduce the amplification efficiency. Therefore, different pre-PCR treatments are being used to reduce the effects of PCR inhibitors. The aim of the present study was to investigate the effects of 16 amplification facilitators to enhance DNA amplification in the presence of ...

Steroid hormones regulate a host of physiological processes and behaviors. These actions can occur by genomic mechanisms involving gene transcription or by nongenomic mechanisms proposed to involve receptors associated with the plasma membrane. BSA-conjugated steroid hormones have been extensively used to elucidate signal transduction pathways for these hormones. We have previously shown, using...

The role of the albumin-carried fatty acids in the induction of tubulointerstitial injury was studied in protein-overload proteinuria. Rats were injected with fatty acid-carrying BSA [FA(+)BSA], fatty acid-depleted BSA [FA(-)BSA], or saline. Macrophage infiltration was measured by immunohistochemical staining, apoptotic cells were detected by in situ end labeling, and proliferating cells were i...

Neoglycoproteins (Lee, Y.C., Stowell, C.P., and Krantz, M.J. (1976) Biochemistry 15, 3956-3963) and monosaccharides which interact with the Man/Fuc receptor (Stah, P.D., Rodman, J.S., Miller, M.J., and Schlesinger, P.H. (1978) Proc. Natl. Acad. Sci. U.S.A. 75, 1399-1403) stimulate lysosomal enzyme secretion in rabbit alveolar macrophages in a dose- and time-dependent fashion. Man43-bovine serum...

A method utilizing bovine serum albumin (BSA) as buffer additive for chiral separation by means of capillary electrophoresis is described. Parameters that affect chiral separation, such as buffer pH, buffer concentration, BSA concentration, and organic modifier, are investigated. Baseline resolution of ephedrine-pseudoephedrine and norephedrine-norpseudoephedrine isomers are achieved in an unco...

The incorporation of a model protein, bovine serum albumin (BSA), into poly(vinyl alcohol) (PVA) hydrogel films during the freezing and thawing process and its subsequent release behavior were investigated. The effect of the number of freezing and thawing cycles as well as the stability of BSA were examined. BSA release profiles were not significantly different from gels prepared after 3 or 5 c...
