Opis

Opis ogólny

β-Lactoglobulin plays a key role in immune response and modulates IgM levels and cell proliferation.[1] β-Lactoglobulin from bovine is a model system for protein folding studies and denaturation kinetics.[2] Polymorphisms in the β-lactoglobulin modulates bovine milk production and composition.[3]

A member of the lipocalin family, βLg is a small protein of 162 amino acids with a molecular mass of ∼18,400 Da,. It has an eight-stranded β-barrel (strands A-H) succeeded by a three-turn a-helix and a final β-strand (strand I) that forms part of the dimerization interface.[4]

Milk from dairy cows contains the protein β-lactoglobulin (BLG). It naturally occurs in a number of genetic variants, and the most prevalent bovine variants are BLG A and BLG B.[5]

Zastosowanie

β-Lactoglobulin from bovine milk has been used:

• for the generation of calibration curve for protein solubility index[6]
• in acid-base titration[7]
• as a standard for surface hydrophobicity analysis[8]

β-Lactoglobulin was used in a cytologic assay for diagnosis of food hypersensitivity in patients with irritable bowel syndrome.[9]

Jakość

Contains β-lactoglobulins A and B which can be isolated chromatographically.
