The interaction between fosfomycin (FOS) and bovine serum albumin (BSA) has been investigated effectively by multi-spectroscopic techniques under physiological pH 7.4. FOS quenched the intrinsic fluorescence of BSA via static quenching. The number of binding sites n and observed binding constant KA were measured by the fluorescence quenching method. The thermodynamic parameters ΔG0, ΔH0 and ΔS0...

Abstract Re(I) complexes have potential in biomedical sciences as imaging agents, diagnostics and therapeutics. Thus, it is crucial to understand how interact with carrier proteins, like serum albumins. Here, two neutral were used ( fac ‐[Re(CO) 3 (1,10‐phenanthroline)L], which L either 4‐cyanophenyltetrazolate (1) or 4‐methoxycarbonylphenyltetrazole ester (2) , study the interactions bovine al...

In the present study, we examined the effect of different two-steps and sequential culture systems, which involve the use of different culture media for early cleavage and later stage embryos, on the development, quality and gene expression profile of bovine embryos generated by in vitro fertilization. Presumptive zygotes were randomly allocated to four different medium treatments without co-cu...

Previous experiments led us to speculate that thyrocytes contain a recycling system for GlcNAc-bearing immature thyroglobulin molecules which prevents these molecules from lysosomal degradation (Miquelis, R., C. Alquier, and M. Monsigny. 1987. J. Biol. Chem. 262:15291-15298). To confirm this hypothesis, the fate of GlcNAc-bearing proteins after internalization by thyrocytes was monitored and co...

Three new rimantadine Schiff bases (RSBs) were prepared, and then the interaction of RSBs with bovine serum albumin (BSA) was investigated using fluorescence, synchronous fluorescence, UV-vis absorption spectroscopy under physiological conditions. The results showed that the three RSBs effectively quenched the intrinsic fluorescence of BSA via static quenching. Binding constant (K a), number of...

Can creatinine clearance in children clear the indexing GFR with BSA from the charge of errors? We read with interest the article of Delanaye and colleagues stating that indexing glomerular filtration rate (GFR) with body surface area (BSA) required mathematical prerequisites to be satisfied, even though many studies reported they were not [1]. Although not the gold standard to measure GFR, cre...

UNLABELLED Allergy to bovine meat and Bovine serum albumin (BSA) is exceptional, especially in the adult life. BSA is considered a minor allergen in cow's milk allergy, but there is little information about this antigen in reactions produced by other beef products as meat. To our knowledge, evolutive studies of beef's allergic patients have not been reported. OBJECTIVE To present one patient ...

Acquired tolerance to BSA in rabbits was terminated following the injection of certain preparations of altered BSA. Injections of Freund's adjuvant containing BSA complexed to anti-BSA, heat-denatured BSA, acetyl-BSA, picryl-BSA, or arsanil-BSA failed to terminate the tolerant state. Except in an occasional tolerant rabbit, injections of these preparations failed to cause the production of prec...

The studies on binding of hexachlorocyclohexane (HCH) with carrier proteins were carried out to establish the role of proteins in the transport of insecticides in insects. Sephadex G-200 column chromatography resolved haemolymph of adult male desert locust, Schistocerca gregaria into three major protein peaks. There was significant binding of gamma-HCH with first protein peak (F1). Two classes ...

An indirect immunoassay for detecting antigen was developed. It was based on fluorescence resonance energy transfer (FRET) and quenching of gold nanoparticles. Bovine serum albumin (BSA) was chosen as model antigen. Fluorescein isothiocyanate (FITC) was attached to anti-BSA antibody (anti-BSA–FITC) as FRET donor, while BSA was conjugated to gold nanoparticles (GNPs–BSA) as FRET acceptor. The fo...
