产品详细介绍 |
简要概述
Z-LETD-FMK是一种细胞渗透性不可逆的caspase蛋白酶8抑制剂,与caspase-8的催化位点结合,在诱导凋亡中起重要作用。Z-LETD-FMK与caspase-8的结合抑制了该蛋白酶的活性,使其能够抑制与caspase-8激活相关的凋亡事件。为了抑制细胞凋亡,应在诱导细胞凋亡的同时添加Z-LETD-FMK。FMK衍生的肽可作为有效的不可逆抑制剂,而不会增加细胞毒性作用。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的Z-LETD-FMK。

储备溶液配制
操作步骤
- 根据需要处理样品以诱导凋亡。
- 添加Z-LETD-FMK。
注意:我们建议使用最终浓度为10-100 µM的Z-LETD-FMK抑制胱天蛋白酶,例如对caspase-8抑制50 µM。
注意:孵育的最佳时间和浓度需要通过实验确定。 - 根据需要对样品染色。
- 用适当的仪器检测荧光强度。
