SA 系列产品

SA-Biotin系统

1963年，Stapley首次从阿维丁链霉菌(Streptomyces avidinii)培养液中分离得到链霉亲和素 (Streptavidin，SA)。作为已知自然界中最强的非共价相互作用之一，SA同源四聚体与生物素（Biotin）可以以高亲合力牢固结合并产生多级放大效应，这使得SA- Biotin系统成为生物化学实验中被广泛应用的宝贵资产。

SA-Biotin系统常被偶联到抗体或蛋白，其中SA偶联标记物如HRP、荧光基团等，Biotin被偶联到抗体或蛋白（MABSOL®生物素标记蛋白），通过SA-Biotin桥连来实现间接检测靶标，广泛用于微量抗原和抗体定性、定量检测及定位观察研究的新技术，使得免疫标记和有关示踪分析更加灵敏。

ACROBiosystems可提供SA系列产品：重组SA蛋白，标记SA蛋白，SA包被板，SA磁珠等，助力您的科研项目和药物研发。
