General description
作为脂质运载蛋白家族的成员，β-乳球蛋白（βLg）是162个氨基酸的小蛋白质，分子量为∼18,400Da。它具有八链β-桶（链A-H），其后面是三转α-螺旋和最终 β-链（链I），其形成二聚化界面的一部分。
来自奶牛的牛奶含有蛋白质 β-乳球蛋白（BLG）。它天然存在于许多遗传变异体中，最普遍的牛变体是BLG A和BLG B。
Application
来自牛奶的β-乳球蛋白用于测试对牛′s 奶过敏的儿童过敏原反应性 CD4 + CD25 + 调节性 T细胞。它还用于测试 Tween 20 从油 - 水和空气 - 水界面的β-乳球蛋白的竞争性置换。

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
