免疫荧光三标?――蓝色荧光的AMCA与Dylight 405标记二抗做免疫荧光实验中,经常要进行免疫荧光的双标记实验,也就是在同一个样本上同时进行两种蛋白的免疫荧光检测。具体的实验时,可以选择不同来源的一抗,然后再选择分别针对一抗的二抗,同时二抗上标记有不同的荧光团。一般的双标记实验里,都会选择一个绿色的(如FITC、Cy2、Dylight 488等)荧光标记,一个红色的(如Rhodamin、Cy ...
荧光二抗的选择――Dylight荧光与传统荧光标记的比较顾名思义,荧光二抗通常指代的就是带荧光团标记的二抗,这样的二抗可以通过观察其在不同波长下荧光的强度来确定其二抗的含量。常见的荧光团包括FITC、Rhodamine、Texas Red、PE、Cy系列等。比如FITC即异硫酸荧光素,是目前应用最广泛的荧光素。最大吸收光波长为490~495nm,最大发射光波长为 520~530nm,呈现明亮的黄 ...
