Technetium labelled Sucralphate has been used as an ulcer scanning agent in the gastrointestinal tract. The labelling described in the literature involves incubation of Tc99m-HSA (Human serum albumin) with Sucralphate. Due to difficulty in obtaining HSA we used bovine serum albumin (BSA) to tag radioactivity with Sucralphate. The radioactive yields (Tagged Sucraiphate and Tc99m-BSA) obtained af...

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...

A formaldehyde-mediated aggregation pathway (FMAP) has been shown to be primarily responsible for the solid-state aggregation of lyophilized formalinized protein antigens [e.g., tetanus toxoid (TT) and formalinized bovine serum albumin (f-BSA)] in the presence of moisture and physiological temperature. Coincorporation of the formaldehyde-interacting amino acid, histidine, strongly inhibits the ...

Background: Coumarins comprise a large family of heterocyclic compounds with benzo-a-pyrone moiety. Objectives: This study aimed to analyze the binding affinity 3-(1H-tetrazol-5-yl) coumarin bovine serum albumin (BSA) and calf thymus DNA (Ct-DNA) using fluorescence spectroscopy. The quenching was recognized during interaction between BSA, followed by static mechanism. Methods: hydrogen bonds, h...

The competitive adsorption of collagen and bovine serum albumin (BSA) on surfaces with varied wettability was investigated with imaging ellipsometry, and ellipsometry. Silane modified silicon surfaces were used as substrates. The results showed that surface wettability had an important effect on protein competitive adsorption. With the decrease of surface wettability, the adsorption of collagen...

Birefringence relaxation studies on bovine serum albumin (BSA) reveal transient decay described by a double exponential process. The values of the relaxation times lead to estimation of the size of the equivalent ellipsoid of revolution for BSA. Previous measurements of transient birefringence for BSA have shown a single relaxation process, since the apparatus used in obtaining those data was n...
