adsorption of bovine serum albumin (bsa) onto calcium hydroxyl apatite (ha), ca10po4(oh)2, has been studied by ultra violet (uv) spectroscopy. the adsorption isotherms of bsa onto the ha surface at 291.7 k and 303.2 k were satisfactorily presented by langmuir equation and the evaluated parameters are reported. the specific surface area of ha has been measured by the bet method. the obtained val...

in this research, effect of bovine serum albumin (bsa) on motility and fertility of indigenous rooster spermatozoa was evaluated using 20 and 48 indigenous roosters and hens, respectively. semen was collected and pooled. in the first experiment, the pooled semen was diluted and divided into four aliquots.the treatments were included the diluted semen without bsa and with 1% bsa; in each group, ...

Tyrosine was explored as a cross-linking agent to form cross-linked bovine serum albumin (BSA) using laccase catalyst. Liquid chromatography-mass spectrometry (LC-MS) and fluorescence spectra indicated that tyrosine can be mainly oxidized dityrosine. Spectra analysis molecular weight were used characterize the BSA treated with laccase. Both SDS-PAGE size exclusion chromatography confirmed forma...

Heat-labile enterotoxin subunit B (LTB) is a non-catalytic protein from a pentameric subunit of Escherichia coli. Based on its function of binding specifically to ganglioside GM1 on the surface of cells, a novel nanoparticle (NP) composed of a mixture of bovine serum albumin (BSA) and LTB was designed for targeted delivery of 5-fluorouracil to tumor cells. BSA-LTB NPs were characterized by dete...

background: active immunization with gonadotropin releasing hormone conjugate (gnrh-bsa) manipulates the fertility axis and thus alters the reproductive cyclicity serum estradiol and progesterone levels. while the application of kamdhenu ark increases the efficacy of gnrh-bsa. objective: this experimental investigation is aimed to evaluate the modulatory effects on estrous cycle serum estradiol...

The interaction of a water-soluble cationic porphyrin, Cobalt(III) 5, 10, 15, 20-tetrakis (1-methylpyridinium-4-yl) porphyrin [Co(III)TMPyP], with bovine serum albumin (BSA) has been studied in 1 mM phosphate buffer pH 7.0 containing 5 mM NaCl by UV-vis absorption, resonance light scattering (RLS) and fluorescence spectroscopies at 25°C. The results of RLS studies represent no aggregate formati...

in this study, the binding of amlodipine (a ca ++ channel blocker) and arsenic (metalloid) to bovine serum albumin (bsa) was studied by equilibrium dialysis(ed) method in order to have an insight into their binding chemistry to bsa. free amlodipine concentration was increased due to addition of arsenic which reduced the binding of the compounds to bsa. however, the free fraction was not increas...

Antibody  based  methods  have  numerous  advantages  compared  to  other  detection  methods. However, heavy metals cannot stimulate the immune antibody response; it is the main obstacle for preparation of the antibodies that used in detection methods of the metals. The production of the immunogenic Pb complexes by using cost benefit linkers of EDTA and DTPA were investigated in this  study.BS...
