一般描述

BCA蛋白测定基于双缩脲作用,即在碱性溶液中蛋白质将Cu2+还原为Cu+,并具有浓度依赖性地检测单价铜离子。二辛可宁酸是一种螯合还原铜的显色剂,产生紫色络合物,在562nm处有很强的吸光度(Smith1985,Wiechelman 1988)。该方法可用于多种样品的蛋白质浓度定量,可在几分钟内进行。

Novagen® BCA蛋白质测定试剂盒可用于在标准测定或微量测定配置中确定20-2000 µg/mL范围内的蛋白质浓度。试剂盒组分足以完成500个标准大小的反应(50 µl蛋白质样品加1 ml试剂)或2500个微量反应(25 µl蛋白质样品加200 µl试剂)。为了方便可靠地制备标准曲线,提供了BSA标准品(2 mg/mL)。

该测定法具有耐用性,可以在许多化合物存在下进行。某些试剂,包括螯合剂、强酸或碱和还原剂,会干扰该测定所依赖的还原和螯合反应(Brown 1989)。BCA测定与以下Novagen蛋白质提取和裂解试剂相容:BugBuster蛋白质提取试剂、PopCulture试剂、CytoBuster蛋白质提取试剂、Reportasol提取缓冲液和Insect PopCulture试剂。试剂盒文献中描述了去除或稀释干扰物质的选项。
BCA蛋白测定法是一种简单可靠的蛋白质定量方法。
