比如,你使用了小鼠IgG1, PE 标记的特异性抗体,那就选用小鼠IgG1, PE标记的非特异性抗体。
下面这个图,是一个比较典型的使用了同型对照的结果图向左转|向右转灰色的曲线是未染色的样本,黄色是同型对照,红色是特异性抗体染色。由于细胞对抗体的非特异性结合,一般同型对照都会比未染色样本的荧光信号要强。所以设置阴性阈值的时候,要根据同型对照,而不是未染色的细胞。
如果一个抗体可以用来“做western blot,免疫荧光,免疫共沉淀,ELISA”,我估计着是HRP或碱性磷酸酶或生物素之类标记的,然后需要再加荧光标记的二抗,这类抗体也是不能做流式用的。
我只用过流式的抗体来做免疫荧光(直接染色),效果还不错,但是反过来就没试过。
楼上两位还是要仔细看下产品说明书
