产品描述

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+,Cu+与BCA试剂形成紫颜色的络合物,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。测定其在562 nm处的吸光值,并与标准曲线对比,即可计算待测蛋白的浓度。该方法快速灵敏、稳定可靠且对不同种类蛋白质变异系数很小。试剂盒中提供了浓度稳定的蛋白标准品用于制作标准曲线。

BCA 蛋白定量试剂盒可用于试管法检测,也可用于微孔板法检测。试管法需较大量蛋白样品(100 μL)和工作液(2 mL),蛋白样品与 BCA 工作液的比率为1:20(v/v),蛋白质测定范围为20-2000 μg/mL,采用加强法可以检测到 5 μg/mL;微孔板法操作简单方便,仅需少量(10-25 μL)的蛋白样品和工作液(200 μL),蛋白样品与工作液的比率为1:20(v/v)或者1:8(v/v),蛋白质测定范围为 20-2000 μg/mL,采用加强法可以检测到 5 μg/mL。

我司提供的 BCA 蛋白浓度检测试剂盒,比色皿法50次,酶标法500次。
