Cell Meter TUNEL细胞凋亡测定试剂盒是一个强大的工具,可方便地检测由DNA的片段化引起的细胞凋亡。该测定是非放射性且快速的。TUNEL测定法使用末端脱氧核苷酸转移酶(TdT)催化TMR-dUTP在片段DNA的游离3'-羟基末端的掺入。通过荧光显微镜(Cy3或TRITC滤光片组)分析所得的TMR标记的DNA。它的红色发射可以方便地与GFP标记的靶标多路复用。荧光TMR标记的核苷酸的直接掺入可显着减少测试步骤。该试剂盒经过优化,可检测固定细胞和福尔马林固定,石蜡包埋的组织切片中的凋亡。

工作溶液配制方案
对于1test,混合以下试剂以使总体积为51 μL;
45 μL TdT反应缓冲液(组分D)
5 μL CoCl 2 (组分C)
0.5 μL TF5-dUTP(组分B)
0.5 μL TdT酶(组分A)。
