描述
One-step TUNEL FITC Apoptosis Detection Kit可以用来检测组织或细胞在凋亡过程中细胞核DNA的断裂情况。细胞内的DNA内切酶在细胞凋亡时激活，切断核小体间的基因组DNA，DNA降解成180 - 200 bp或其它整数倍片段。基因组DNA断裂产生的3'-OH末端，在末端脱氧核苷酸转移酶（Terminal Deoxynucleotidyl Transferase, TdT）作用下在其末端添加上带标记的dUTP，从而可以在荧光显微镜或流式细胞仪下进行检测，Ex/Em=492 nm/517nm。
本试剂盒应用范围广泛，可以用于检测冷冻或石蜡切片中的细胞凋亡情况，也可以检测培养的贴壁细胞或悬浮细胞的凋亡情况。
组份和存储
Place product at -20 °C for storage; Among them, FITC-12-dUTP Labeling Mix, stored at -20 °C protected from light.特性
293A cells were divided into three groups: control group, Positive group using DNase I treatment, Apoptosis group using 10μM Camptothecin treatment. After 12 hours of treatment, TUNEL kit (K1133) was used to detect cell Apoptosis.
