Purpose A caspase-9 inhibitor
Sequence Z-Leu-Glu(OMe)-His-Asp(OMe)-FMK
Characteristics PubChem CID: 44135217
A synthetic peptide that irreversibly inhibits caspase-9 and related caspase activity. The inhibitor is designed as a methyl ester to facilitate cell permeability. (CAUTION: If the intended use is on purified or recombinant enzymes, esterase should be added to generate free carboxyl groups).
Purity > 98 % by HPLC
Chemical Name Z-LEHD-fluoromethylketone
Formula C₃₂H₄₃FN₆O₁₀
Permeability Cell-permeable
Solubility DMSO
Molecular Weight 690.71 Da
Application Notes Centrifuge the vial prior to opening. We recommend using 1000-5000X dilutions for inhibiting caspase-9 activity in cell culture (e.g., Add 1 µL to 1-5 mL of culture medium). The optimal doses may vary for different cells and culture conditions.
Restrictions For Research Use only
Format Liquid
Concentration 10 mM
Handling Advice Protect from light and moisture
Storage -20 °C
Expiry Date 12 months
