Human Isocitrate Dehydrogenase (IDH1), also known as oxalosuccinate decarboxylase, GenBank Accession No. NM_005896, full length [a.a.1-414(end)] with Arg to His mutation on aa132 and C-terminal FLAG-tag, MW= 48kD, expressed in Sf9 cells via a baculovirus expression system.
Specific Activity
57pmol/min/ug
Assay Conditions
IDH reductive activity was measured in 200ul reaction containing 25mM Tris (pH 7.4), 150 mM sodium chloride, 10mM MgCl2, 0.03% BSA, 1mM alpha-Ketoglutarate, 10uM NADPH and IDH. Depletion of NADPH was monitored continuously at 340nm for 20 minutes. Molar extinction coefficient of NADPH is 6,200 M-1cm-1
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Other applications not tested.
Recommended Dilutions
Optimal dilutions to be determined by the researcher.
