In Vitro
Pharmacology

The nature of the molecule, the biology being investigated, and the overall requirements for throughput and yield, determine the in vitro testing decision. Aragen skilled scientists work with customers to develop and implement assays best suited for their specific research requirements. We offer a diverse portfolio of cell-based and biophysical assays that enable the development and characterization of new therapeutics, based on the physical characterization of the protein (expression, size, weight, binding), as well as biological activity in mammalian cells, and ultimately, in animals.

Our cell biology team has extensive experience in developing cell-based assays for determining mechanisms of action, evaluating potential therapeutics, and screening small libraries of compounds. The protein sciences team provides a range of analytical methods using multiple assay platforms to characterize therapeutic, diagnostic or reagent-grade proteins.
