常用二抗(总表)002
二抗在免疫学实验中起着举足轻重的作用,二抗的选择也决定了整个实验的成败。实验中在选择二抗时必须注意以下几点:(1) 一抗种属来源,主要根据一抗种属来源来决定确定二抗的类型,如一抗是小鼠来源,那二抗就买抗小鼠的即可(如羊抗小鼠、兔抗小鼠等均可)。
(2)标记物的选择。一般来讲,耦联到二抗上的探针主要有酶(辣根过氧化酶HRP和碱性酶AP或其衍生物APAAP,PAP),荧光基团(FITC, RRX, TR, PE)和生物素。选用哪种探针的二抗主要取决于具体的实验。对于western blot和ELISA,常用的二抗是酶标二抗,而细胞或组织标记实验(细胞免疫化学,组织免疫化学,流式细胞术)中通常使用荧光基团标记的二抗,免疫组化中也可以使用辣根过氧化酶或碱性酶标记的二抗。如果想要更大程度的放大检测信号,可以使用biotin/avidin检测系统。
友科生物可以提供多种常规二抗,质优价廉,欢迎选购。
