一般描述
IgA抗体是分泌性抗体，大量存在于胃肠道，呼吸道和泌尿生殖道的黏膜内壁，泪液，初乳和唾液中。因此，分泌性IgA有助于抵抗粘膜表面病原体的体液防御机制。
通过分级分离和离子交换分级分离从合并的正常人初乳中纯化人IgA。
通过分级分离和离子交换分级分离从合并的正常人初乳中纯化人IgA。
应用
纯化的IgA可用作ELISA、斑点免疫结合、免疫印迹、免疫扩散和免疫电泳等多种免疫测定的参照抗原、标准品、封闭剂或外壳蛋白。其他应用包括作为制备免疫原和固相免疫吸附剂的起始物料。来自人初乳的IgA用作ELISA（1 mg/ml）和凝胶电泳的标准品。
重悬
用缓冲盐水复溶（150mM 氯化钠）。

Mucosa-associated lymphoid tissue (MALT) specifically protects mucosal surfaces. In a previous study of the human conjunctiva, evidence was also found for the presence of MALT in the lacrimal sac. The present study, therefore, aims to investigate its morphology and topographical

IgA is the most prevalent antibody type on mucosal surfaces and the second most prevalent antibody in circulation, yet its role in immune defense is not fully understood. Here we show that IgA is carried inside cells during virus infection
