1.标准曲线的标准品是否一定要梯度稀释,为什么?我试过非梯度稀释的,也可以达到线性R2=0.99.
2.我用了CurveExpert做标曲,自动搜索后发现有10种提供的方程,各种形式的,其中一个十分适合我的实验结果(LogisticModel),而其他的感觉又不适合,因为结果常常为负值。这又是为啥捏?
3.实验的酶标仪最大OD值可以测到4,如果我的测量结果在1.3,是否像其他人所说的>1了就不准确了。
4.利用夹心法进行定量分析是否一定要使用线性方程?
不好意思啊,一下问了这么多问题,最近做了一个月的ELISA,完全摸不清头脑啊。谢谢各位了
在这种测定方法中有3种必要的试剂:①固相的抗原或抗体(免疫吸附剂) ②酶标记的抗原或抗体(标记物)③酶作用的底物(显色剂)
测量时,抗原(抗体)先结合在固相载体上,但仍保留其免疫活性,然后加一种抗体(抗原)与酶结合成的偶联物(标记物),此偶联物仍保留其原免疫活性与酶活性,当偶联物与固相载体上的抗原(抗体)反应结合后,再加上酶的相应底物,即起催化水解或氧化还原反应而呈颜色。
其所生成的颜色深浅与欲测的抗原(抗体)含量成正比。 这种有色产物可用肉眼、光学显微镜、电子显微镜观察,也可以用分光光度计(酶标仪)加以测定。其方法简单,方便迅速,特异性强。向左转|向右转
ELISA双抗体夹心法(enzyme linked immunosorbent assay——sandwich technique)的原理是将特异性抗体结合到固相载体上形成固相抗体,然后和待检血清中的相应抗原结合形成免疫复合物,洗涤后再加酶标记抗体,与免疫复合物中抗原结合形成酶标抗体-抗原-固相抗体复合物,加底物显色,判断抗原含量。
