TUNEL FITC Apoptosis Detection Kit
绿色荧光 TUNEL 凋亡检测

石蜡切片、冰冻切片、贴壁和悬浮培养细胞的凋亡检测

· 经过优化FITC-12-dUTP 与未标记dNTP 的比例,提高了荧光检测的信噪比和灵敏度
· 高活性的重组TdT 酶保证荧光掺入效率
· 适用于细胞爬片、石蜡切片和冰冻切片

本试剂盒采用TUNEL (TdT mediated dUTP Nick End Labeling) 法,应用末端脱氧核糖核苷酸转移酶(Terminal Deoxynucleotidyl Transferase,TdT) 在凋亡细胞断裂的DNA的3’- 羟基(3’-OH) 末端催化掺入荧光素-12-脱氧三磷酸尿苷(FITC-12-dUTP)。FITC-12-dUTP 标记的DNA 可以用荧光显微镜直接观察或者用流式细胞仪定量。试剂盒对标记反应进行了优化,采用一定比例的FITC-12-dUTP 和未标记dNTP 进行3’-OH 末端的核苷酸掺入,使得同一个断裂的DNA 片段末端可以形成更长的“标记尾巴”,减少了相邻掺入dNTP 上标记基团的空间位阻,增加每个断裂片段上的荧光基团数目,降低荧光基团相邻后可能造成的聚集和淬灭,提高了荧光检测的信噪比和灵敏度,高活性的重组TdT 酶保证荧光掺入效率,适用于细胞爬片、石蜡切片和冰冻切片。

文献和实验Detection of Apoptosis by the TUNEL Assay
Apoptosis is the name given to a normal cell process—that of programmed cell death. As the term implies, this is normally a well controlled and highly regulated series of events leading to the elimination of an “unwanted” cell
Detection of Apoptosis by TUNEL Assay
Terminal deoxynucleotidyl transferase (T dT) dU TP N ick-E nd L abeling (TUNEL) assay has been designed to detect apoptotic cells that undergo extensive DNA degradation during the late stages of apoptosis. The method is based on the ability
