General description
过硫酸铵(APS)是生物化学和分子生物学中被广泛用于制备聚丙烯酰胺凝胶的一种试剂。APS通过一种碱催化的机制在水溶液中形成氧自由基。最常用作催化剂的碱是叔胺,例如TEMED(N,N,N′,N′-四甲基乙二胺)或DMAPN(3-二甲基氨基丙腈)。这些自由基将会引起丙烯酰胺和双丙烯酰胺的聚合而形成凝胶基质,其可用于通过大小对大分子进行的分离。APS还用于通过光引发交联化学研究蛋白-蛋白间相互作用。
Application
过硫酸铵已用于制备聚丙烯酰胺凝胶和丙烯酰胺水凝胶。
丙烯酰胺凝胶聚合催化剂。
Analysis Note
经过测试可用于丙烯酰胺聚合反应。
