- Individually expressed recombinant human CYP isoforms (rhCYPs), including CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4.
- Human CYP isoforms responsible for metabolism of test compound determined by measuring metabolic intrinsic clearance (CLint) in the presence of individual rhCYPs.
|Test Compound Concentration||1 µM|
|Incubation Time||0, 5, 10, 15, 30, and 45 minutes|
|Number of Repeats||2|
Study Report: Contribution of individual rhCYPs to overall metabolism of test compound (in %) calculated from measured CLint values based on abundance of respective CYPs in liver and corresponding intersystem extrapolation factors (ISEF).1
Test Compound Requirement: 1-2 mg dry powder or 100-200 µL of 10 mM DMSO stock solution.
