产品特性
- Members of the caspase family play key roles in inflammation and mammalian apoptosis. Z-FA-FMK is a negative control inhibitor which has no inhibitory effect on apoptosis mediated by caspases and can only inhibit cysteine proteases (those not requiring P1 Asp inhibitors) such as Cathepsin B. Z-FA-FMK has a molecular weight of 386 Daltons. Flow cytometric analysis of apoptosis in Jurkat cells (Human T-cell leukemia, ATCC TIB-152). Jurkat cells were preincubated with the following: no inhibitor (upper left and bottom left panels), 20 μM Z-LEHD-FMK (a caspase-9 inhibitor) (upper center and bottom center panels) or 20 μM Z-FA-FMK negative control inhibitor (upper right and bottom right panels) for 30 minutes, and then either left untreated (bottom row) or treated with 4 μM campthothecin for 3 hours (top row). Following incubation, cells were collected and stained with PE Annexin V (Cat. No. 559763) to identify cells undergoing apoptosis. The results indicate that in campthothecin treated cells, approximately 42 % of the cells were induced to undergo apoptosis and the use of the negative control inhibitor, Z-FA-FMK, showed similar results to the treated cells without inhibitor (right panels), indicating that the negative control inhibitor did not attenuate apoptosis.
