      Z-DEVD-FMK, Caspase-3 Inhibitor
      Z-DEVD-FMK, Caspase-3 Inhibitor
      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-DEVD-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 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 caspase-3 inhibitor Z-DEVD-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 attenuate apoptosis.

      Preparation And Storage

      Avoid multiple freeze-thaws of product.

      Store the lyophilized Z-DEVD-FMK inhibitor at -20˚C. Reconstitute the Z-DEVD-FMK inhibitor in DMSO before use. The reconstituted Z-DEVD-FMK inhibitor may be stored in small aliquots at -20˚C.

      Recommended Assay Procedures

      The Z-DEVD-FMK inhibitor is designed to be used in both in vivo and in vitro cell based assays to measure the inhibition of apoptosis. Reconstitute 1.0 mg of Z-DEVD-FMK inhibitor in DMSO. A 10 mM stock solution may be made by dissolving 1.0 mg of Z-DEVD-FMK in

      150 µl DMSO. The final concentration of inhibitor may vary between experimental systems and investigators are encouraged to titrate the inhibitor for optimal performance. As a precautionary note, do not exceed a final DMSO concentration of 0.2% as higher levels may cause cellular toxicity and mask the effect of the caspase inhibitor.

      Antibody Details
      Down Arrow Up Arrow

      Members of the caspase family play key roles in inflammation and mammalian apoptosis. Z-DEVD-FMK is an irreversible and cell permeable inhibitor of caspase-3. 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-3 activity and to study events downsteam of caspase-3 activation. Z-DEVD-FMK has a molecular weight of 668 Daltons.

      Purified
      Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
