Gallery: Z-VAD(OMe)-FMK #60332
Z-VAD(OMe)-FMK is supplied as a lyophilized powder. For a 10 mM stock, reconstitute the 1 mg of powder in 213.9 μl of DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used as a pre-treatment at 5-100 μM for 1 hr.Storage: Store lyophilized or in solution at -20ºC, desiccated. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.
The synthetic peptide Z-VAD(OMe)-FMK is a cell permeable, irreversible pan-caspase inhibitor that displays non-cytotoxic effects (1-4). Z-VAD(OMe)-FMK prevents caspase-3 from adopting its active form and thereby blocks apoptosis (5). Research studies show that Z-VAD(OMe)-FMK also inhibits other enzymes, including cathepsin B, PNGase, and picornaviral 2A proteinases (6-8). Additional studies demonstrate that Z-VAD(OMe)-FMK can inhibit mitogen-induced T cell proliferation (2,9,10).
