Hepregen Products & Services
The ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology Applications
The Hepregen Product Line
Ascendance Biotechnology proudly manufactures and provides the same Hepregen micro-liver HepatoPac® and HepatoMune™ cell-based assays and continues the world-class Solutions via Service™ contract services you have come to expect from Hepregen. The Hepregen products and services utilize proprietary “Cell Micropatterning Technology” developed at the Massachusetts Institute of Technology that creates islands of living liver cells in a “sea” of living stromal cells and are compatible with modern day, high-throughput drug screening techniques. The Hepregen line of human, rat, monkey, dog, and multi-species/multi-donor application-directed cell-based assays are driving a paradigm shift in drug development and have been validated in collaboration with investigators at several well-known pharmaceutical companies.
Human HepatoPac® kits are an ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology applications. Begin dosing as early as 2 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).
Satisfaction Guaranteed! Every kit is backed by Hepregen’s performance guarantee and professional customer scientific support. If you are unable to produce desired results in your lab, Hepregen’s scientists will run your compounds through our our in-house pipeline.
HepatoMune™ is a highly functional in vitro liver platform that models inflammation-mediated hepatotoxicity. HepatoMune contains the proprietary patterning of hepatocyte “islands” in a “sea” of stromal with the addition of Kupffer cells to mimic the physiological microenvironment of the liver, enabling innate response to cytokine-mediated drug-induced liver injury. Its proven longevity of at least 10 days provides the experimental time needed to analyze the inflammatory response and its mechanisms of action.”
Human HepatoMune™ in vitro tri-cultures remain viable and highly functional for 10 days. These tri-cultures secrete albumin, synthesize urea, display functional bile canaliculi, and metabolize compounds using active Phase I and Phase II drug metabolism enzymes. The presence of functional Kupffer cells in HepatoMune™ tri-cultures is confirmed via pHrodo-S. aureus phagocytosis and CD68 staining. Primary hepatocyte function remains unaffected by the presence of activated Kupffer cells.
HepatoPac® B-CLEAR® Transporter Kits
B-CLEAR® technology ensures that the functioning hepatic transporters provide the most physiologic intracellular concentrations.
The HepatoPac® B-CLEAR® Transporter Kit combines the proven B-CLEAR® technology and contains Transporter Certified™ human hepatocytes, providing a standard for hepatocyte function and ensuring reproducibility from experiment to experiment. Transporter Certified™ hepatocytes have characterized uptake and efflux drug transport that result in physiologic intracellular concentrations, the driver for all intracellular processes. HepatoPac® B-CLEAR® Transporter Kits.
B-CLEAR® technology refers to a patented methodology that — when applied to properly functioning hepatic cells in culture — opens the bile pockets (analogous to bile canaliculi in vivo), allowing material that has been transported from inside the cell to be measured. Measuring biliary efflux provides the ability to evaluate biliary clearance, transporter interactions, and intracellular concentration. The B-CLEAR® technology is patented in over 45 countries worldwide and has been optimized over 10 years of work, ensuring that the primary hepatocytes are properly polarized with functioning uptake and efflux transporters. No other technology can deliver this level of transporter activity measurement, and therefore provide the most physiologic intracellular concentrations possible.
- Superior Drug Transporter Function
- Bile pockets are formed and maintained consistent with liver physiology
- Uptake and Efflux activities are robust and balanced
- Robust Transporter and P450 Activity and Expression
- Expression and Activity levels are reproducibly maintained
- Culture Longevity Supporting Chronic Exposure
Rat HepatoPac® kits are an ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology applications. These kits come in a ready-to-use format of Rat HepatoPac®; co-cultures micropatterned on industry-standard 24- and 96-well plates for streamlined, higher throughput in vitro assays. A variety of rat kits are available to cover all your application and size needs, and contain everything you need to conduct your assays. Begin dosing as early as 3 days after receiving the kit!
Monkey HepatoPac® kits are an ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology applications. These kits come in a ready-to-use format of monkey HepatoPac® co-cultures micropatterned on industry-standard 24- and 96-well plates for streamlined, higher throughput in vitro assays. A variety of monkey kits are available to cover all your application and size needs, and contain everything you need to conduct your assays. Begin dosing as early as 3 days after receiving the kit!
Dog HepatoPac® Co-cultures are an ideal way to conduct all your DMPK, Predictive Toxicology & Mechanistic Toxicology applications. This model system is available as a Custom Research Service and in kit format for Metabolic Identification and Profiling.
Run all your DMPK & Toxicology assays using primary hepatocytes from either human, rat, monkey or dog. Run two or more species on a single plate! These unique multi-species microplates are a plug-and-play product able to simultaneously collect data from two or more species in a single experiment providing the highest efficiency approach to predicting likely in vivo outcomes.
Custom Multi-Species HepatoPac® Kits
Hepregen offers custom plates combining available species (Human, Rat, Dog, Monkey) according to your project plan.
Solutions via Services
Solutions via Services™ for DMPK Services or Toxicology Services are for those scientists who, out of necessity or convenience, choose to outsource their in vitro research and development projects. Ascendance will continue Hepregen’s premiere Contract Research Services using the same expert staff and facilities. Nothing has changed except our name!
