一般描述

蛋白A是金黄色葡萄球菌的细胞壁成分，分子量为56kDa。它具有五个结合结构域，可与Fc或Fab片段的免疫球蛋白重链发生相互作用。蛋白A可激活补体系统、干扰素产生、超敏反应和细胞介导的细胞毒性作用。辣根过氧化物酶是一种含血红素的酶。 在过氧化氢存在下，该酶催化鲁米诺的氧化。

特异性

仅与大多数哺乳动物的IgG结合，除了大鼠、山羊、绵羊。

应用

来自金黄色葡萄球菌/辣根的蛋白A-过氧化物酶已用于酶联免疫吸附测定（ELISA）。

包装

包装规格基于蛋白含量。

外形

冻干粉末，含有柠檬酸钠缓冲盐。通过A205测定蛋白质。

制备说明

通过改良O′Sullivan, M.J., et al., FEBS Lett., 95, 311 (1978)中所报道的有利于低分子量偶联物的实验方法，使用VI型过氧化物酶标记细胞外蛋白A。
