Co-culture comprised of cryopreserved primary Rabbit hepatocytes cultured with cells of non-parenchymal, stromal type.
Example Metabolic Activity (nmoles/hr/106 cells)
| Substrate | Enzyme | Concentration (µM) | Day 1 | Day 4 | Day 8 |
| 7-Ethoxycoumarin | Phase I (ECOD) | 100 | 3.35 | 2.74 | .94 |
| 7-Hydroxycoumarin | Phase II (UGT) | 100 | 295.33 | 278.50 | 265.33 |
| 7-Hydroxycoumarin | Phase II(Sult) | 100 | 48.17 | 37.83 | 30.65 |
Culture Condition and Morphology
Cryopreserved rabbit hepatocytes were thawed and plated with HUREL PlatinumHeps™ Media supplemented with 10% serum and subsequently changed 24 hours post-seeding to HUREL PlatinumHeps™ maintenance Media. CYP substrate concentrations are given in the table above along with metabolite formation recorded as nmoles/hr/million cells. All incubations were carried out in triplicate on days 1, 4, and 8 (customer day) upon cell delivery and incubated for 60 minutes. Reactions took place in a humidified incubator at 37°C, in 5% CO2. Collected supernatants were stored at -20°C until further LC/MS/MS analysis.
