Key ADMET Products

999Elite™ Hepatocytes

The premiere cryopreserved primary hepatocytes selected to enhance the efficiency of drug metabolism, toxicology, and pharmacology



Human and animal liver microsomes available in many pooled lot sizes including UltraPool™ (HLM) . These pooled microsomes enable consistency in experimental results in multi-site and long-term programs by delivering reproducible data across multiple CYP and UGT enzymes.


MetMax™ Hepatocytes

Pioneered by Discovery’s Dr. Albert Li, Gentest® MetMax™ human hepatocytes are the optimal in vitro experimental systems for evaluating drug metabolism.


Tissue Fractions

Gentest® microsomes, cytosol, and S9 subcellular fractions provide a convenient, cost-effective source of native enzymes responsible for phase I and phase II metabolism of drugs. 



Gentest® Supersomes™ are recombinant enzyme products and recognized as the industry gold standard. They contain higher catalytic activities than native human liver enzymes.



Gentest® TransportoCells™ products are high-performance mammalian cells in a convenient, cryopreserved format that transiently over express a single human SLC transporter protein.
