Cell-based assays are important experimental tools in life science research and biomanufacturing. They are based on cell culture methods in which living cells are grown in vitro and used as a model system to assess the biochemistry and physiology of healthy and diseased cells. Cell culture assays provide a method to quantitatively analyze the presence, number, or functional activity of cells or tissues of interest. Both standardized and customized cell-based assays are widely used by scientists for numerous applications as cost-effective and reproducible research tools. For example, cell culture assays are critical in preclinical drug discovery, and recently emerging technologies such as 3D cell culture and pluripotent stem cells help improve compound efficacy and toxicity screening predictions.

Our scientific team works with you to determine the best assay design for your needs. Our assay development experience covers a broad range of research objectives, tailoring each test study for sponsor relevance by selecting the correct cellular system, stimuli, time points, and endpoint readouts to fit the research objectives. We have experience working with a variety of cellular backgrounds, from easy-to-transfect cell lines （e.g., HEK 293, 293FT, HCT116, or HeLa) to difficult-to-transfect cell lines （e.g., fibroblasts, neuroblastoma-derived, hepatocytes carcinoma, bone marrow-derived and endothelial-derived cells).
