Description
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.

Preparation and Storage
Avoid multiple freeze-thaws of product.Store the lyophilized Z-IETD-FMK inhibitor at -20°C. Reconstitute the Z-IETD-FMK inhibitor in DMSO before use. The reconstituted Z-IETD-FMK inhibitor may be stored in small aliquots at -20°C.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols.
The Z-IETD-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 the Z-IETD-FMK inhibitor in DMSO. A 10 mM stock solution may be made by dissolving 1.0 mg of Z-IETD-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 effects of the caspase inhibitor.
