The objectives of this s tudy were to test the effects of four levels of bovine serum albumin (BSA) on the development of ovine embryos cultured in Brinster's and Whitten's media and to examine the extent of in vitro development of ovine embryos cultured from various cell stages. Two hundred and forty-three oneto 16-celi ovine embryos were cultured in Brinster's medium (BMOC-2 plus .1% w/v dext...

To evaluate the re lat ionship be tween tumor burden and c i rculat ing immune complexes (IC) in ch i ldren with neurob lastoma (NBL), we studied sera col lected at intervals from pat ients with d isseminated (Stage III or IV) NBL. Sera from 10 of 12 pat ients conta ined IC by the Raji cell assay at some time dur ing the first 9 to 11 months of the study. H igher IC levels were observed in sera...

The interaction of the dye reactive bright red 6C with bovine serum albumin has been investigated. Formation of a complex between reactive bright red 6C and bovine serum albumin was detected by use of absorption difference spectroscopy. The curves obtained by titration of the protein against the dye were recorded at different pH and ionic strength of the solution. An unusual form of titration c...

The interaction of bovine serum albumin ( BSA) and egg albumin with water solublephthalocyanine, cobalt (ΙΙ) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( CoTSPc) , has been studiedby the UV- Vis method at pH 7.0 and five different temperatures 20, 25, 30, 35 and 40°C. Theformation constants have been elucidated by using spectrophotometric titration and computerSQUAD program data refinement. Th...

Dietary flavonoids show beneficial effects in the prevention of chronic diseases. However, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. In the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (BSA) were investigated by fluorescence spectroscopy. The binding affinities of t...

Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...

Background: Progress in the field of biology and biochemistry has led to the discovery of numerous bioactive peptides and proteins in the last few decades. Delivery of therapeutic proteins/peptides has received a considerable amount of attention in recent years. Methods: In this study, a two-step desolvation method was used to produce biodegradable hydrophilic gelatin nanoparticles (GNP) as a d...

In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...

We analyse two cases of Bovine Serum Albumin (BSA) allergy. The first regards a female laboratory technician with a history of bronchial asthma due to cat allergy, who developed an exacerbation of bronchial symptoms as a consequence of BSA powder inhalation at work. To date, sensitization to BSA as a cause of occupational asthma has rarely been reported in the scientific literature. The second ...
