Fragmentation of Bovine Serum Albumin by Pepsin

Fragmentation of Bovine Serum Albumin by Pepsin. I. the Origin of the Acid Expansion of the Albumin Molecule.

A long series of studies has shown that serum albumin changes very markedly, though reversibly, certain of its physicochemical properties over the pH range 4 to 2 (1). The sedimentation constant (I), translational diffusion coefficient (2), rotational relaxation time (3, 4), and specific viscosity and specific optical rotation (5) all show changes of considerable magnitude. To this list low ang...

Quantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles

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 ...

Relationship between the conformation of bovine serum albumin and its digestion by pepsin.

Interaction of Phthalocyanine with Egg albumin and Bovine serum albumin

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...
