General description
A member of the lipocalin family, β-Lactoglobulin (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.
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.
Application
β-Lactoglobulin from bovine milk was used to test the allergen-responsive CD4+ CD25+ regulatory T cells in children who have outgrown cow′s milk allergy. It is also used to test the competitive displacement of β-lactoglobulin by Tween 20 from oil-water and air-water interfaces.
Preparation Note
Crystallized
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.

Immunochemical detection of food allergens is usually based on the use of polyclonal or monoclonal immunoglobulins G (IgG) antibodies. However, due to differences in epitopes recognition between IgG and IgE, an epitope modification during food processing can potentially alter allergenicity

The hygiene hypothesis implies that the increasing prevalence of allergy in 'westernized' countries is explained by reduced bacterial exposure in early life, but the underlying mechanism remains elusive. We therefore wanted to study the effect of bacterial lipopolysaccharide (LPS) on
