HepatoSure® is a pool of human hepatocytes designed to facilitate your DMPK applications with a consistent hepatocyte product over time (years). HepatoSure® is best suited for both discovery and development of ADME-Tox study assays where generation and comparison of data is required. Let’s take a closer look, and you might like to benefit from our current offer to try these for yourself (see below).
Sekisui XenoTech has just established a method for high Aldehyde Oxidase and Xanthine Oxidase activity in pooled Human liver test systems.
These new test systems (Pooled Human Liver S9 and cytosol) have been prepared from tissue treated to preserve high Aldehyde Oxidase (AO) and Xanthine Oxidase (XO) activity, yet without significantly impacting major cytochrome P450 (CYP) activity.
If you are looking for enzymatic in vitro tools for drug metabolism, reaction phenotyping, metabolite generation, using pig as model, you may find these newly released Pig Bactosomes from Cypex of interest.
Bactosomes are recombinant enzymes expressed in E. coli with a patented expression system that enables expression of drug metabolising enzymes without the need for large modifications to be made to the proteins. They demonstrate excellent batch-to-batch consistency and robust activity levels. Each batch is characterized for linearity with time and CYP concentration, Km and Vmax.
These cell lines transiently express the current FDA and EMA recommended SLC drug transporters (eg. OCT1 and OCT2; OAT1 and OAT3; MATE1; MAT2K…). Conditioned as cryopreserved format, they provide flexibility for experimental planning and can be assayed in just 2 days.
