Z-Vad-fmk, non-methylated Usage And Synthesis

Description

Z-VAD(OH)-FMK is an irreversible tripeptide inhibitor of all caspases. This non-methylated form is useful in studies involving recombinant, isolated, or purified enzymes. Unlike the methylated form, Z-VAD(OMe)-FMK , this compound does not require pretreatment with esterases prior to in vitro use.

Uses

Z-VAD-FMK (Z-VAD(OH)-FMK) is a well-know pan caspase inhibitor, which does not inhibit ubiquitin carboxy-terminal hydrolase L1 (UCHL1) activity even at concentrations as high as 440 μM[1].

General Description

An irreversible general caspase inhibitor. Useful for studies involving recombinant, isolated, and purified caspase enzymes. Unlike Caspase Inhibitor I (Cat. No. 627610), this inhibitor does not require pretreatment with esterase for in vitro studies. A 10 mM (1 mg/221 μl) solution of Caspase Inhibitor VI (Cat. No. 219011) in DMSO is also available.

Biochem/physiol Actions

Product does not compete with ATP.

IC 50

Caspase
