The formation of the textures on the surface of the films from the solutions of bovine serum albumin (BSA) with sodium halides (NaF, NaCl, and NaBr) of various concentrations was studied. The formation of symmetric zigzag textures on the surface of BSA films (Cryst Eng 3:173-194, 2000) in the presence of sodium halides depends on the conformational state of the protein globule. Thermal denatura...

Abstract Background Natural products play a key role in treating different ailment including diabetes, asthma, skin diseases, and cancer. It is well known that synthetic drugs elicit significant toxicity when used the clinic. A higher drug affinity towards carrier protein Bovine Serum Albumin (BSA) would enhance bioavailability which turn leads to therapeutic efficacy. The focus of present stud...

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...

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...

The aim of the present study was to examine the adsorption of bovine serum albumin (BSA) to hydroxyapatite surfaces by means of zeta potential. The electrophoretic mobility of both hydroxyapatite and BSA were negative, with BSA itself less negative than hydroxyapatite. The zeta potential of the surface of BSA-adsorbed hydroxyapatite was significantly more negative than that of hydroxyapatite al...

Background Patients with eosinophilic esophagitis (EEo) have a prior history of atopy. Skin prick test(SPT) is able to identify the allergens involved, allowing a correct dietary approach, in order to achieve the remission of sympthoms and discontinue swallowed costicostheroids. Allergy to bovine meat and especially to Bovine serum albumin (BSA) is exceptional in adult life, but can be a cause ...

using uv-vis spectrophotometric method the interaction of water soluble phthalocyanine, cobalt(ιι) 4,4′,4′′,4′′′- tetrasulfophthalocyanine(cotspc), with bovine serum albumin (bsa) to determine the formation constant and related thermodynamic functions. the measurements were considered in 1mm sodium phosphate buffer, ph 7.0 and at 5 different temperatures 20, 25, 30, 35 and 40ºc. the results sho...

We demonstrate label-free molecule detection by using an integrated biosensor based on a Si(3)N(4)/SiO(2) slot-waveguide microring resonator. Bovine serum albumin (BSA) and anti-BSA molecular binding events on the sensor surface are monitored through the measurement of resonant wavelength shifts with varying biomolecule concentrations. The biosensor exhibited sensitivities of 1.8 and 3.2 nm/(ng...

Here, we investigated the interaction of cuminaldehyde with a model carrier protein, bovine serum albumin (BSA). The formation BSA–cuminaldehyde complex was confirmed through ultraviolet–visible (UV–Vis) spectroscopy and further proven by detailed intrinsic fluorescence spectroscopic measurements. As observed, quenched tryptophanyl BSA. data, before analyses, were corrected for inner filter eff...

Steady state fluorescence measurements have been used for the investigation of interaction between the bovine serum albumin (BSA) and fluorescence probes: 3-hydroxy-2,4- bis[(3-methyl-1,3-benzoxazol-2(3H)-ylidene)methyl]cyclobut-2-en-1-one (SQ6), 3-hydroxy- 2,4-bis[(3-methyl-1,3-benzothiazol-2(3H)-ylidene)methyl]cyclobut-2-en-1-one (SQ7) and 3-hydroxy-2,4-bis[(1,3,3-trimethyl-1,3-dihydro-2H-ind...
