产品描述
Ac-DEVD-CHO是一种合成四肽,是II类caspases-caspase-3/7的有效抑制剂,Kis分别是0.23和1.6nM。常用来抑制凋亡细胞内的caspase-3/7活性,以及研究caspase-3/7活化后的下游事件。另外,Ac-DEVD-CHO还能抑制其他caspases,对caspases-1/-2/-4/-5/-6/-8/-9和-10的Kis分别是18、1710、132、205、31、0.92、60和12 nM[1]。

细胞类型(Cell type):Osteoclast-like cells (OCLs) 实验方法(Assay):OCLs were incubated with RANKL followed by different concentrations of SIN (0.5 and 1 mmol/L) or camptothecin (4 μmol/L) with or without Ac-DEVD-CHO (10 μmol/L)for 24 h. Camptothecin was used as a positive control to induce apoptosis. Caspase-3 activity in the cells was measured using the caspase-3 colorimetric activity assay kit. |

动物模型(Animal Model):Ischemia Model of Male Sprague–Dawley rats weighing 250 to 300 g 实验方法(Assay):A 20mM solution of Ac-YVAD-CHO and Ac-DEVD-CHO in DMSO was prepared, and 2 μl of the solution was injected into the vitreous cavity with a 30-gauge needle 24 hours before ischemic insult.Another 3 μl was injected into the vitreous at the time of reperfusion. As a control, DMSO (vehicle) was injected in the same way. Twenty-four hours after reperfusion, eyes were enucleated, and TUNEL staining was performed. |
