Protein A简介

Protein A杂质的监管状态
《中华人民共和国药典》2020年版第三部《人用重组单克隆抗体制品总论》3.2.4 工艺相关杂质中提出“采用适宜的方法对供试品宿主蛋白质、宿主细胞和载体DNA、蛋白A及其他工艺相关杂质进行检测”。

《尼妥珠单抗注射液》3.1.3.3 蛋白质A残留量中提出“用酶联免疫吸附法(通则3429)测定,蛋白质A残留量应不高于蛋白质总量的0.001%”。

USP<130> PROTEIN A QUALITY ATTRIBUTES中提到希望厂家能够在纯化工艺中将脱落的protein A清除,生产工艺也需要进行相应验证。基于ELISA的残留检测基本上已被应用于工艺研发和验证过程中以确保在蛋白A亲和层析之后的过程步骤中能够有效去除残留蛋白A。此外,制造商应通过原材料鉴定和柱寿命研究,对树脂和配体质量有明确的了解和文件记录。
