Cyp in vitro 代謝試験
WebCYP inhibition is measured in both direct and dependent assays. A CYP-selective substrate is used, at a concentration of substrate that achieves half the maximum reaction velocity (K m) for each CYP enzyme (see below). Known inhibitors are used as positive controls for both direct and metabolism-dependent inhibition assays.
