General description

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.[1]

Application

β-Lactoglobulin was used in a cytologic assay for diagnosis of food hypersensitivity in patients with irritable bowel syndrome.[2]

Biochem/physiol Actions

A member of the lipocalin family, βLg is a small protein of 162 amino acids with a molecular mass of ∼18,400 Da. It features 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.[3]

Preparation Note

Chromatographically purified

Analysis Note

May not contain folate binding protein; not recommended for folate analysis.

Other Notes

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

Previous work indicated that conformational changes of β-lactoglobulin (β-LG) induced by dynamic high pressure microfluidization (DHPM) was related to the increase of antigenicity. In this study, β-LG glycated with 1-kestose and combined with DHPM decreased the antigenicity of β-LG. The
