    说明

    一般描述:来自奶牛的牛奶含有β-乳球蛋白(BLG)。它天然存在许多遗传变异体,最普遍的牛变异体是BLG A和BLG B。

    应用:β-乳球蛋白被用于细胞学检测,以诊断肠易激综合征患者的食物超敏反应。

    生化/生理作用

    βLg是脂质运载蛋白家族的成员,它是由162个氨基酸组成的小分子蛋白,分子量约为18400Da。它具有由八条链组成的β桶状结构(A-H链),桶外存在一个具有三个转角的a螺旋和第九条β链(I链),其形成二聚体形成界面的一部分。

    其他说明:含β-乳球蛋白A和B,可通过色谱法分离。

    质量:可能不含叶酸结合蛋白;不推荐用于叶酸分析。

    制备说明:色谱纯化产品

    Cow's milk allergy (CMA) is a common food allergy, especially among infants and young children. Approximately 85% of milk-allergic children outgrow their allergy by the age of three but the remaining 15% remain allergic. Bovine beta-lactoglobulin (BLG) is one of

    Food & function, 11(7), 6038-6053 (2020-06-20)
    The effect of binding of flavonoids, (-)-epigallocatechin-3-gallate (EGCG) and green tea extract (GTE), to beta-lactoglobulin (β-Lg) and micellar casein (micellar casein isolate, MCI) on protein digestibility was investigated. β-Lg resisted digestion by pepsin, but in the presence of EGCG the

    Comparison of antigenicity and conformational changes to β-lactoglobulin following kestose glycation reaction with and without dynamic high-pressure microfluidization treatment.
    Junzhen Zhong et al.

    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
