(2 references)-
- Application
- Functional Studies (Func), Cell Culture (CC), Blocking Reagent (BR), Inhibition Assay (InhA)
- Purpose
- A pan-caspase inhibitor
- Brand
- BD Pharmingen™
- Sequence
- Z-Val-Ala-Asp(OMe)-FMK
- Characteristics
- Members of the caspase family play key roles in inflammation and mammalian apoptosis. Z-VAD-FMK is a cell permeable general caspase inhibitor that irreversibly binds to the catalytic site of caspase proteases and inhibits apoptosis. The peptide is O-methylated in the P1 position on aspartic acid providing enhanced stability and increased cell permeability. Z-VAD-FMK has a molecular weight of 467 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-VAD-FMK (upper center and bottom center panels) or 20 μM negative control inhibitor (Z-FA-FMK, upper right and bottom right panels) (Cat. No. 550411) for 30 min, and then either left untreated (bottom row) or treated with 4 μM of campthothecin for 3 hr (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 general caspase inhibitor Z-VAD-FMK reduced the level of apoptosis to that observed in the untreated control. Cells treated with Z-FA-FMK (Cat. No. 550411) showed similar results to the campthothecin treated cells without inhibitor, indicating that the negative control inhibitor did not attenuate apoptosis.
