Cytochrome p450 assay
Web1. Recent guidance from the US Food and Drug Administration (USFDA) has advocated testing of time-dependent inhibition of cytochrome P450 (CYP), which can be addressed by performing IC(50) shift as well as K(I)/k(inact) determinations. 2. Direct (IC(50), K(i)) and time-dependent inhibition (IC(50) s … WebPlease provide an overview of Cyprotex's Cytochrome P450 (CYP) Inhibition Ki assay. Compounds are evaluated incubating up to 6 inhibitor concentrations, (spanning the IC 50 determined using Cyprotex's Cytochrome P450 Inhibition IC 50 assay), and 5 substrate concentrations, spanning the K m, in duplicate.
