一般描述

卵清蛋白占蛋清蛋白总量的75%。[1]
鸡蛋清白蛋白是蛋白的主要蛋白成分。鸡蛋清白蛋白是磷酸化糖蛋白。根据氨基酸序列,分子的肽部分由 385 个残基组成,分子量为 42.7kDa。[2]

应用

清蛋白(源于鸡蛋清)还用于研究输液(初乳乳清、牛奶乳清、羊水)对于胎猪肠道卵清蛋白 (OVA)吸收的影响。[3]
磷酸化糖蛋白,可用作蛋白质电泳的标记物(~45kDa)。已被用于生产哮喘的动物模型。

生化/生理作用

差示扫描量热法表明鸡蛋清白蛋白在 84℃ 下变性。[4]卵清蛋白可作为载体蛋白与合成肽结合,用作免疫原。
清蛋白(源于鸡蛋清)可作为天然的粘附剂。[5]

Questions

  1. What does 62-88% (agarose gel electrophoresis) mean exactly? is this the purity of the protein or something else? I want to know what the purity of albumin is per mg of powder.

    1 answer
    1. The specification states that each lot of this product will be 62-88% albumin as verified by agarose electrophoresis. The exact percentage will be found on the lot specific certificate of analysis.
