一般描述

链霉亲和素得名于它的细菌来源亲和素链霉菌 和母鸡蛋清蛋白亲和素,而后者与生物素有很高的亲和力。其同源核与亲和素具有33%的序列相似性,并具有共同的四聚体结构。这是一种晶体四聚体蛋白,分子量为4*15000Da。它可结合四种生物素分子。链霉亲和素缺乏碳水化合物和含硫氨基酸。
链霉亲和素是从亲和素链霉菌中分离得到的一种结晶蛋白,具有生物素结合能力。它有四个生物素(如亲和素)结合位点并可结合四个生物素分子。链霉亲和素现被视为一种新型的生物素结合蛋白。

应用

来自抗生物素蛋白链霉菌的链霉亲和素已用于:
  • 的线性官能化
  • 链霉亲和素捕获酶联免疫吸附测定(ELISA)
  • 微泡制备
