产品描述
Z-DEVD-FMK是一种具细胞膜渗透性、不可逆的caspase-3抑制剂。对caspase-3的抑制,使其能抑制caspase-3活化后下游凋亡事件的进程,从而阻断凋亡发生。Z-DEVD-FMK能抑制肿瘤细胞凋亡。体内对癫痫发作后的大鼠海马组织起到神经保护作用。
本Z-DEVD-FMK的天冬氨酸P1位点进行O-甲基化修饰,即:Z-DEVD(OMe)-FMK,使其稳定性和细胞膜渗透性都得以提高。一旦进入细胞,内源性酯酶水解甲基基团,产生具生物活性的肽。本品可用于体内和体外细胞实验。

注意事项
1)第一次溶解粉末配制储存液时,请根据单次使用次数分装冻存,一定要避免反复冻融,以保证产品的活性不受影响。
2)-20℃冻存的储存液从冰箱取出后,可在25℃水浴锅温育片刻直到全部融解,离心后待用。
3)对于caspase激酶实验(如纯化或粗提取的caspase),Z-DEVD-FMK需要与待测样品预孵育10-20min,再进行后续测定。【注意】:本品为经甲基化处理的Z-DEVD-FMK,需先用酯酶(esterase)处理去除甲基化基团后,再进行体外激酶实验。
4)本品仅用作科研用途,不得用作临床诊断或治疗,不得用于食品或药品,绝对禁止用在人身上。
5)为了您的安全和健康,请穿实验服并戴一次性手套操作。

体内研究(动物模型): 动物模型(Animal Model):Male Sprague Dawley rats with Brain trauma 实验方法(Assay):DMSO (5 μl) vehicle or z-DEVD-fmk (160 ng in 5 μl of DMSO) was administered at a controlled rate of 0.5 μl/min via an infusion pump at 30 min before and at 6 and 24 hr after TBI. At the designated time periods after injury, animals were decapitated under sodium pentobarbital anesthesia (100 mg/kg, i.p.), and the brains were removed rapidly and dissected. |
