Caspase-8 Inhibitor Z-IETD-FMK

Application: Functional Studies (Func), Enzyme Activity Assay (EAA)

Catalog no.: ABIN412377

Additional Information

Immunogen: Sequence: Z-Ile-Glu-Thr-Asp-FMK (FMK, fluoromethyl ketone)

Description: A synthetic peptide that irreversibly inhibits FLICE and related protease/caspase activity and blocks apoptosis. IETD is the specific recognition sequence found in CPP32 proenzyme. The inhibitor is designed as a methyl ester to facilitate cell permeability.

Molecular Weight: 654.0

Application Details

Application Notes: We recommend using 5000X dilutions for inhibiting caspase-8 activity in Jurkat cell culture (e.g., Add 1 l to 5 ml of culture medium). The optimal doses may vary for different cells and culture conditions.

Purity: >99% by HPLC analysis.

Buffer: 20 l Z-IETD-FMK (10 mM) in DMSO

Storage: Store at –20 o C. SHELF LIFE: 1 year under proper storage conditions

Restrictions: For Research Use only
