SR-VAD-OPH in vitro Apoptosis Detection Reagent

ICT offers a set of inhibitor reagents that employ an O-phenoxy (OPH) reactive group instead of an FMK group. In a manner analogous to the FMK class of cysteine reactive compounds, the OPH inhibitors form a stable covalent thioether adduct with the reactive SH-site of caspase enzymes present in apoptotic cells. These reagents are used as simple and reliable methods for screening apoptosis in live cells in tissues. SR-VAD-OPH (SR-Val-Ala-Asp(OMe)-Oph (2,6-diF) poly caspase inhibitor) can be used with a fluorescence microscope, fluorescent plate reader, or flow cytometry.
