产品简介：
 BCA蛋白浓度测定试剂盒(BCA Protein Assay Kit)是常用的两种蛋白浓度检测方法之一BCA法研制而成。BCA法的原理：在碱性条件下蛋白质分子中肽键结构与Cu2+络合并将Cu2+还原成Cu1+。BCA特异地与Cu1+结合形成稳定的蓝紫色复合物，在562nm处有最大的光吸收值并于蛋白质浓度成正比。该测定法实现了蛋白浓度测定的简单，高稳定性，高灵敏度和高兼容性。
BCA法测定蛋白浓度不受绝大部分样品中的化学物质的影响，可以兼容样品中高达5%的SDS，5%的Triton X-100，5%的Tween 20,60,80。但受螯合剂和略高浓度的还原剂的影响，需确保EDTA低于10mM，无EGTA，二硫苏糖醇低于1mM，β-巯基乙醇低于0.01%。不适用BCA法时建议试用GBCBIO Technologies生产的Bradford蛋白浓度测定试剂盒(G3722)。

产品特点：
○灵敏度高，检测浓度下限达到25μg/ml，检测下限达到0.5μg
○在50-2000μg/ml浓度范围内有较好的线性关系
○受样品中离子与去污剂的影响小
○可用酶标仪或分光光度计进行检测
储存和稳定性:
BCA试剂A和B室温保存，蛋白标准请-20℃冻存。本试剂盒自订购之日起一年内有效。
