产品特性

Members of the caspase family play key roles in inflammation and mammalian apoptosis. Z-IETD-FMK is an irreversible and cell permeable inhibitor of caspase-8. The peptide is O-methylated in the P1 position on aspartic acid providing enhanced stability and increased cell permeability. This inhibitor can be used to inhibit caspase-8 activity and to study events downstream of caspase-8 activation. Z-IETD-FMK has a molecular weight of 654 Daltons. Flow cytometric analysis of 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-IETD-FMK (upper center and bottom center panels) or 20 μM of a negative control inhibitor Z-FA-FMK (upper right and bottom right panels) for 30 minutes, and then either left untreated (bottom row) or treated with 4 μM of 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 camthothecin treated cells, approximately 42 % of the cells were induced to undergo apoptosis and the use of the caspase-8 inhibitor Z-IETD-FMK reduced the level of apoptosis to that observed in untreated controls. Cells treated with Z-FA-FMK (Cat. No. 550411) showed similar results to the treated cells without inhibitor, indicating that the control inhibitor did not attentuate apoptosis.
