FAM-FLICA® Caspase-1 (YVAD) 检测试剂盒是ImmunoChemistry公司开发的一款检测试剂盒,该产品采用荧光抑制剂探针FAM-YVAD-FMK标记活细胞中的活性caspase-1酶。
研究认为,Caspase在细胞凋亡和炎症中通常起重要作用。而ICT开发的这款检测试剂盒就可以用来检测caspase活性来定量细胞凋亡。FAM FLICA Caspase-1探针能够检测Caspase-1是否处于活化状态。FLICA试剂FAM-YVAD-FMK能够进入每个细胞并且会不可逆地与活化的caspase-1结合。FAM-YVAD-FMK FLICA试剂会共价偶联活性酶,使得它保留在细胞内,而没有结合的FAM-YVAD-FMK FLICA试剂则会被洗脱。通过绿色荧光信号可以对细胞中存在的活性caspase-1酶活性进行直接测量。含有结合FLICA的细胞可以通过酶标仪、荧光显微镜或流式细胞术进行分析。
FAM-FLICA的最佳激发波长为488-492nm,峰值发射波长为515-535nm。
在长通滤波器下观察碘化丙啶(PI),激发波长为488-492nm,发射波长为610nm;核结合的PI的最大发射波长为617nm。
使用紫外滤光片来观测Hoechst 33342,激发波长为365nm,发射波长为480nm。

2'3'-cGAMP检测试剂盒是cayman公司的一种竞争性检测试剂盒,可用于细胞裂解液、血浆、血清和
组织样本中2'3'-cGAMP的定量。
环GMP-AMP合成酶(cGAS)是一种细胞质DNA传感器,用于检测哺乳动物细胞细胞质中核酸的存在,
作为细菌或病毒感染的指标。cGAS催化合成第二个信使2'3'-cGAMP,从细胞质ATP和GTP响应dsDNA
结合。然后,2'3'-cGAMP与干扰素基因的适配器蛋白刺激因子(STING)紧密结合,导致TBK1的募集和
随后的IRF3磷酸化。IRF3诱导I型干扰素的转录和翻译。cGAS的激活和2'3'-cGAMP的产生在宿主防御
中起重要作用,但也可能在自身免疫性或炎症性疾病中发挥作用。调节cGAS活性,随后抑制或诱导2'3'
-cGAMP的形成,是药理学干预的一个活性靶点。
该试剂盒的检测范围为6.1pg/ml-100ng/ml (9pM-148.3nM),中点(50%B/B)约900pg/ml
(1335pM),灵敏度(80% B/B)约为85pg/ml (126pM)。
