Primary rat hepatocytes that had been cryopreserved were thawed, plated on HUREL PlatinumHeps™ Media supplemented with 10% serum, and then switched to HUREL PlatinumHeps™ maintenance Media 24 hours later.
The concentrations of CYP substrates are listed in the table above, and metabolite formation is expressed as nmoles/hr/106 cells. On days D1, D4, and D8, after cell delivery, all incubations were performed in triplicate and incubated for 60 minutes.
The reactions happened in a humid incubator with 5% CO2 at 37 °C. Until a subsequent LC/MS/MS analysis, collected supernatants were kept at –20 °C.
