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。

样品实验方案

以下是我们推荐的方案,仅提供指导。具体实验应根据您的特定需求进行修改。

 

溶液配制

储备溶液配制

Z-LETD-FMK储备溶液配制:在Z-LETD-FMK中添加适量的DMSO,制成2-5 mM Z-LETD-FMK储备液。注意:将未使用的Z-LETD-FMK储备溶液分装在-20°C下。

 

操作步骤

  1. 根据需要处理样品以诱导凋亡。
  2. 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。
  3. 根据需要对样品染色。
  4. 用适当的仪器检测荧光强度。
