ICT FAM-FLICA 轻松检测活细胞Caspase-1 (YVAD) 活性

       Caspase全称为含半胱氨酸的天冬氨酸蛋白水解酶(cysteinyl aspartate specific proteinase)。caspase是一类蛋白酶家族，成员较多，在人类，已经鉴定了11种不同的caspase，根据其蛋白酶序列的同源性可分为3个亚族：Caspase-1亚族包括 Caspase-1、4、5、11；Caspase-2亚族包括Caspase-2、9； Caspase-3亚族包括Caspase-3、6、7、8、10。起细胞凋亡执行者作用的是caspase3,6,7。   

       Caspase-1在介导炎症反应和细胞焦亡(pyroptosis)中发挥重要作用。市面上常见的是检测细胞裂解液中的Caspase-1活性，更多研究者希望动态检测 活细胞 内的Caspase-1的活性，做更真实的实验！艾美捷科技为您推荐Immunochemistry Tech（ICT）品牌专利FLICA系列产品。 

        ICT的FLICA?检测法使研究人员能够在体外对活细胞内的Caspase酶家族进行针对性地活性进行定量和监测。  

* 仅供科研使用，不得用于医疗. 

        【原理】FLICA试剂FAM-YVAD-FMK（Ex/Em = 488nm/530nm），是无细胞毒性的，细胞膜渗透抑制剂。进入每个细胞，并不可逆地与活化的caspase-1结合。任何未结合的FAM-YVAD-FMK-FLICA试剂扩散出细胞并被冲走。因此留在细胞内的绿色荧光直接体现了活性caspase-1酶活性的。荧光结果可通过荧光酶标仪、荧光显微镜、流式细胞仪进行分析。
