一般描述

高亲和力生物素结合蛋白(Kd 约为10-15),其在宽的pH和温度范围内可保持稳定。每个链霉亲和素分子可结合4个生物素分子。链霉亲和素缺乏存在于亲和素上的碳水化合物侧链,并具有接近中性的等电点(pI为5.5-6.5,亲和素为10)。因此,链霉亲和素通常显示出比亲和素更低的非特异性结合水平。1%溶液在280 nm处的消光系数为32。
高亲和力的生物素结合蛋白。

警告

毒性:标准处理(A)

单位定义

一个单位定义为在pH 7.0条件下,结合1.0 µg D-生物素所需的链霉亲和素的量。

重悬

以终浓度的两倍在H₂O或1 mM NaHCO₃(pH 9.0)中重溶,然后用等体积的2X缓冲液进行稀释。
重溶后,等分并冷冻长期保存(-20°C),或冷藏(4°C)短期保存。水溶液在4°C下可稳定保存6个月,在-20°C下可保存长达2年。
