选用和特异性抗体同种亚型的,同样荧光素标记的抗体,采用同样的染色步骤染同样浓度的细胞。然后上机检测。如果细胞有非特异性的结合,那同型对照的荧光强度可能会比未染色的阴性对照要高一些。
同型对照只用于那种阳性和阴性之间没有明确分解的情况。如果阳性细胞群非常清楚,是不需要同型对照的。另外,在多色同染的情况下,也不采用同型对照,而是采用FMO(fluorensence minus one)对照。
另外,对于同型对照的使用,也有很多反对意见。就算是同型抗体,也可能会有不同的亲和力,并不一定就能真实反应非特异性的结合。

其同型为;percp-cy5.5(25ug包装)浓度:0.2mg/ml,
那么如果CD45RA抗体如果加入20ul,那同型抗体应该加入多少ml:
我自己的初步计算是:1ul的3分之1.不知道我算对了吗?应该怎么加才好呢?
