产品简介

goodOmni-Rapid快速蛋白定量试剂盒的原理与传BCA蛋白定量法类似,但采用了一种不同BCA(Bicin-choninic Acid)全新特殊的螯合剂,从而实现了对蛋白质浓度进行快速、稳定、灵敏的测定。其原理是在碱性环境下蛋白质分子中的肽Cu2+成络合物,将Cu2+还原成Cu+,Cu+与螯合物结合,从而发生颜色反应本试剂盒中的螯合剂可敏感特异地与Cu+结合,只需室温孵5 min即可形成稳定的橙黄水溶性复合物,而传BCA法则需37下孵30 min才可完成颜色反应该橙黄色的复合物480 nm处有光吸收值,颜色的深浅与蛋白质浓度成正比,可根据吸收值的大小来测定蛋白质的含量。本试剂盒含有一系列浓度的蛋白质标准品溶液(BSA溶液),即取即用,无需稀释,方便快捷。

使用说明

good◈以微孔酶标仪法为例:
gooddd1. 配置显色工作液:
gooddd1. a. 计算显色工作液总量:
goodgoodgoodd工作液总量 = (BSA标准品样本个数待测样本个数)×复孔数×每个样本显色工作液体积
gooddd1. a. 举例:BSA标准品样本个数8个,待测样本个数3个,复孔3个。
goodgoodgoodd显色工作液总量 = (8BSA标准品样本3个待测样本)×3个复孔×200 μL(每个样本工作液体积) = 6.6 mL
gooddd1. b. 根据计算出的显色工作液需要总量,将试剂A和试剂B50:1的体积比,配制显色工作液,充分混匀。
gooddd1. b. 注意1 剂B刚加入试剂A时,会出现灰蓝色沉淀,但只需混匀几秒钟,沉淀就会消失,形成透亮的绿色溶液;
gooddd1. b. 注意2)建议工作液现用现配,在室温下,工作液会逐渐变为深绿色,但只要1.5 h内使用,对定量的准确性不会造成影响;
gooddd1. b. 注意3) 由于加样可能存在误差,建议配制BCA工作液时,多配1~2个孔。

gooddd2. 定量检测

gooddd3. (2)用1×PBS或0.9%生理盐水将样品适当稀释(可以多作几个梯度,2倍、4倍、8倍稀释)20 μL96孔板的样品孔中;
gooddd3. (3)各孔加入200 μL显色工作液,充分混匀,盖96孔板盖,室温5min,即可进行检测;
gooddd3. (3)注意由于颜色反应速度较快,须保证20~30 min之内完成读值如果必须30 min后才能读值,可提前加50 μL 1 M HCl终止反应。
gooddd3. (4)用酶标仪测定每个样品及BSA标准品A480注意要减去空白对照( 标准品① 工作液)的A480;
gooddd3. (5)绘制标准曲线,计算样品中的蛋白浓度。
gooddd3. (3)注意:数据处理时需要去除明显错误的值。待测样品浓度可以从标准曲线中查得, 实际浓度需要乘以样品的稀释倍数。如果是计算机绘制的曲线,可以从计算机给出的线性方程式计算出待测样品的浓度。

注意事项

good1. 本产品可以采用酶标仪(微孔检测法)或者分光光度(试管检测法)测定蛋白浓度,使用普通的分光光度计测定,需根据比色皿的最小检测体积,适当加BCA工作液的用量使不小于最小检测体积,样品和标准品的用量可相应按比例放大也可不变。使用分光光度计测定蛋白浓度时,每个试剂盒可以测定的样品数量可能会显著减少;
good2. 建议每次测定蛋白样品时,都须绘制标准曲线,以获得准确数据;
good3. 完成室温孵育5 min后,须20~30 min内完成检测,否则会影响蛋白定量的准确度;
good4. 如待测样品中含较多的干扰物质(具体见附表),可采用其它蛋白定量产品;
good5. 为了您的安全和健康,请穿实验服并戴一次性手套操作;
good6. 本产品仅限科研使用。
