Ability of a Micropatterned Hepatocyte Co-culture System to Generate Major Human Drug Metabolites

Hepregen Corporation
8 May 2014

This case study demonstrates the increased success of Hepregen’s HepatoPac system in identifying primary and secondary circulating and excretory metabolites when compared to liver microsomes, S-9 fractions and primary human hepatocyte suspensions for a series of 27 compounds with known in vivo human metabolite profiles.

Human HepatoPac™ Kits

Hepregen Corporation

Human HepatoPac™ kits are an ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology applications. Begin dosing as early as 3 days after receiving the kit! Use our Human HepatoPac™ Triple Donor plates for the ultimate in convenience. HepatoPac™ co-cultures derived from 3 independent and highly characterized donors are provided on a single plate (8-wells from each donor).HepatoPac™ kits can be used for any assay that can be run using sandwich, monoculture plates or suspension cultures. Due to the extended in vitro functionality of HepatoPac™ co-cultures, Hepregen kits enable studies such as low turnover clearance or chronic toxicity studies that could not otherwise be performed.Human HepatoPac™ Kits Features: HT-ready format; 24- and 96-well plates Proprietary micropatterened co-culture Superior data for both slowly and rapidly metabolized drugs Culture longevity of up to 4 weeks Kits contain: Human HepatoPac™ Co-Cultures Maintenance Media Application-specific Media and additives Instructions for culture maintenance and application-specific protocols On-site customer training included

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.ADME-ToxicologyADME-toxicology (ADME-Tox) studies are used in pharmacology and pharmacokinetics to assess the activity/toxicity of drugs <i>in vivo</i> or <i>in vitro</i>. Find bioassays for absorption, distribution, metabolism, and excretion of drug molecules including cytotoxicity, transporter/permeability, metabolism and activity assays as well as hepatocytes and cell lines for ADME. Find the best ADME-toxicology products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.MetabolomicsMetabolomics is the study of small metabolites (the intermediates and products of metabolism). It involves the identification and quantification of cellular metabolites using analytical technologies such as GC, HPLC, NMR, and LC/MS.Drug DevelopmentDrug development refers to the process of bringing a new drug to market.
