A critical stage in the drug discovery process is studying the absorption, distribution, metabolism and excretion (ADME) of drug candidates. These kinetic studies, together with screening for drug toxicity, help to build a pharmacological profile of the drug.

Case Study: ADME/Tox Screening in 3D Culture

Learn how Swansea University Medical School is using 3D liver cell models to study cell viability and metabolic activity for nanomaterial hazard testing.

Assays for ADME/Toxicity

Bioluminescence-based assays offer considerable time savings in drug ADME/Tox screening, compared to conventional methods. Background is minimal compared to fluorescence-based assays, since there is no naturally occurring source of bioluminescence in most cell lines. Cell-based CYP metabolism assays can be adapted to 3D cell culture with optimized protocols.
