Purpose A caspase-4 inhibitor
Sequence Z-Leu-Glu(OMe)-Val-Asp(OMe)-FMK
Characteristics PubChem CID: 44135220
A synthetic peptide that irreversibly inhibits activity of LEVD-dependent caspases (e.g., caspase-4). The inhibitor is designed as a methyl ester to facilitate cell permeability. The product can be used for both in vitro and in vivo studies. (CAUTION: If the intended use is on purified or recombinant enzymes, esterase should be added to generate free carboxyl groups).
Purity > 95 % by HPLC
Chemical Name Z-LEVD-FMK, Caspase-4 Inhibitor (fluoromethylketone)
Formula C₃₁H₄₅FN₄O₁₀
Permeability Cell-permeable

Application Notes We recommend using 1000-5000X dilutions for inhibiting caspase-4 and related caspase activity (e.g., Add 1 µL to 1-5 mL of culture medium). However, the optimal doses may vary for different cells and culture conditions. The inhibitor is designed as a methyl ester to facilitate cell permeability.
