Virtual Conference Exhibition: Drug Discovery and Toxicity Testing


Toxicity testing is paramount when screening newly developed drugs to advance them through the development pipeline. Using the right cell-based models and assays for such testing in the early stages of your research can help reduce late-stage attrition.

STEMCELL Technologies is here to bolster your drug development and toxicity testing research. With personalized services, custom products, flexible delivery times, and the option to reserve entire lots to pre-screen cells for applications, we help you get the ethically sourced, human primary cells you need. In addition, our Contract Assay Services (CAS) specialize in primary cell-based assays and can work with you to design and perform your drug development studies.

Browse scientific presentations and resources below to learn about our human primary cells, Contract Assay Services, or other products and services for customized, flexible solutions to support your unique regulatory or product requirements.
