BCA Protein Quantification Kit BCA蛋白浓度测定试剂盒(增强型)
产品介绍
BCA(Bicinchoninic acid)法是目前应用比较广泛的蛋白质浓度测定方法。基于双缩脲反应,即在碱性环境下蛋白质将Cu2+还原成Cu+,产生一种紫蓝色复合物,在562 nm处有高的吸光值,该反应产物的量与蛋白质浓度成正比。BCA蛋白浓度测定法实现了蛋白质浓度测定的简便、灵敏、快速和稳定性。试剂盒中提供的蛋白标准品为用户制作标准曲线提供了便利。
该BCA蛋白浓度测定试剂盒可用于比色皿法检测,也可用于微孔板法检测。前者虽需较大量(100 μL)的蛋白样品,但由于其在检测中使用蛋白样品与BCA工作液的比率为1:20(v/v),从而降低干扰物质带来的影响。后者操作简单方便,仅需少量(10-25 μL)的蛋白样品。不过,由于其在检测中使用蛋白样品与BCA工作液的比率为1:8(v/v),某种程度上限制干扰物质的承受浓度以及降低最低检测水平。我司提供三种规格的BCA蛋白浓度检测试剂盒,比色皿法分别可做50次,250次,500次。酶标法分别可做500次,2500次,以及5000次。
