Z-VAD-FMK (Cell permeable)
|Synonyms||Z-VAD(OMe)-FMK; Z-Val-Ala-DL-Asp(OMe)-FMK; pan-Caspase Inhibitor|
|Purity Chemicals||≥95% (HPLC)|
|Solubility||Soluble in DMSO, acetonitrile or dimethyl formamide.|
|Other Product Data||
Prepare a 10mM stock solution of the caspase inhibitor in high quality DMSO. Add 2μl of stock solution to 1ml of culture medium containing cells to give 20μM final concentration. Effective final concentrations are estimated to be 5-20μM. If a particular inhibitor is applied at higher concentrations, specificity for an individual caspase or even for the caspase family (>100μM) might be compromised. DMSO concentrations above 0.2% may cause cellular toxicity, thus masking the effect of the caspase inhibitor. For in vivo or in vitro experiments extending 12-48 hours, fresh inhibitor may have to be added (injected) due to inactivation of the inhibitor by endogenous cysteine proteases.
