Cell-Based Assay Kits

Cell-Based Assay Kits are a necessity for investigating cellular health, behavior, and response under nearly any condition. They bring all the reagents, detection strategies, buffers you require and let you quantitate proliferation, viability, apoptosis, cytotoxicity, differentiation, or other functional readouts in intact cells. The leading kits give you reproducible signals, well-calibrated controls, and minimal background so you spend less time troubleshooting and more time reading real biology.
