Technical Data
Z-VAD-FMK (Cell permeable) (Z-VAD(OMe)-FMK, pan-Caspase Inhibitor, Z-Val-Ala-DL-Asp(OMe)-fluoromethylketone, Benzyloxycarbonyl-Val-Ala-DL-Asp(OMe)-fluoromethylketone)
Biochemicals Storage: 4C/-20CShipping: Blue Ice
Cell-permeable, non-selective broad-spectrum caspase inhibitor. Binds irreversibly to the catalytic site of caspase proteases.
The peptide is O-methylated in the P1 position on aspartic acid, providing enhanced stability and increased cell permeability.
Inhibits ICE-family protease/caspase processing, leading to apoptosis and autophagy induction.
Decreases proteasome activity.
Potent inhibitor of caspase-1 activation in NLRP3-induced cells.
Used in apoptosis and inflammasome studies.

Storage and Stability:
Short-term Storage: +4C
Long-term Storage: -20C
Stable for at least 3 years after receipt when stored at -20C.
