Clinically relevant drug-drug interactions (DDI) are a serious concern for any new drug development project. To better support capturing the multiple mechanisms of DDI potential using cryopreserved primary human hepatocytes, we now offer Interaction Qualified Cryopreserved Human Hepatocytes (Catalog HUCPI) which are characterized for 3 major mechanisms of DDI: Transporter activity Enzyme activity Enzyme gene induction potential. Interaction Qualified Cryopreserved Human Hepatocytes have the following features and benefits: Benefits Use the same donor for basal clearance, transport, and induction studies Actual rates of transport reported rather than relative rates for less ambiguity Large lots mean fewer rounds of testing so you can focus on results Prequalified in Lonza media for better reproducibility Features*: Confluent monolayer with cobblestone morphology, distinct nuclei, and tight junctions for 5 days or more Inducibility of enzyme activity for CYP3A4, CYP2B6, and CYP1A2 Inducibility of mRNA for CYP3A4, CYP2B6, CYP1A2, and CYP2C8 genes Actual rate of uptake or efflux for OATP1B1/3, OCT1/2, NTCP, and BSEP** transporters Differences in passive vs. active uptake for OATP1B1/3, OCT1/2, and NTCP transporters. Basal metabolism for 8 CYPs, SULT, UGT, and aldehyde oxidase Plated low-turnover clearance for CYP2C9, CYP2D6, and CYP3A4 Complementary thawing, plating, and maintenance medium available > 5 million viable cells/vial Characterized for long-term culture potential (> 7 days) Characterized for spheroid formation potential Benefits Use the same donor for basal clearance, transport, and induction studies Actual rates of transport reported rather than relative rates for less ambiguity Large lots mean fewer rounds of testing so you can focus on results Prequalified in Lonza media for better reproducibility Pre-tested for long-term culture, spheroid formation, and 96-well compatibility Applications Drug-Drug interaction studies Low clearance metabolism studies Drug uptake and efflux Disease modeling Xenotransplantation Short term cellular toxicity studies 3D cell culture Content & Storage Content Cryopreserved ampule of HUCPI containing >5 million viable cellsOur qualification methods for cryopreserved human hepatocytes are modelled after recommendations from the FDA publication In Vitro Metabolism and Transporter Mediated Drug-Drug Interaction Studies Guidance for Industry (2017, http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.h™).
