采用抗-HBe抗体包被反应板,加入校准品及被测样本,同时加入定量HBeAg中和抗原,经过振荡孵育,洗板后再加入铕标记的抗-HBe,若标本中抗-HBe浓度高,HBeAg将被大量中和,使最后形成的抗-HBe-HBeAg-铕标记抗-HBe复合物减少。增强液(β-NTA)将标记在抗体上的Eu3+解离到溶液中,Eu3+和增强液中的有效成分形成高荧光强度的螯合物,荧光强度和样本中的抗-HBe浓度成反比。
GM实验:试剂说明书上要求20分钟显色,10分钟的时候看一下,差不多就可以加终止液,但是我的标曲显色特别快,2分钟最低浓度蓝色就就深了,此时样本颜色还很浅很浅,我只能一块儿加终止液。所以,标曲显色过快,可能是什么原因?
(ps:第一列是标曲,后面是样本)
