β-Lactoglobulin was used in the identification of the genetic variants of κ-casein in milk by isoelectric focusing electrophoresis.

β-Lactoglobulin was used in the identification of the genetic variants of κ-casein in milk by isoelectric focusing electrophoresis.

β-Lactoglobulin B (β-LG B), a isoform of β-Lactoglobulin, is a small protein of 162 amino acids with a molecular mass of 18.2 kDa and optimum pH of 5.2. It is present in high level in casein and is relatively low in raw bovine milk. β-LG has eight-stranded β-barrel (strands A-H) succeeded by a three-turn α-helix and a final β-strand (strand I), that forms part of the dimerization interface.

β-Lactoglobulin B (β-LG B) show less inhibitory effect on the Staphylaococcus sp compared to β-LG A.
