Consider Eurofins DiscoverX’s custom development capabilities for custom cell lines, assays, & enzyme development.
Eurofins DiscoverX® offers over 730 optimized ready-to-use (RTU) assay kits are provided with frozen-ready cells, eliminating the need for cell culture when performing cell-based functional or binding assays with sensitivity and run-to-run reproducibility your programs depend on. These quantitative, robust assay kits use a homogeneous, no-wash protocol, and are provided in various phase-appropriate formats, from basic research and drug discovery through clinical development, and into commercial release and stability programs for potency testing.
The extensive menu of target-based assays covers a broad range of target classes including GPCRs, kinases, cytokine and immune checkpoint receptors, intercellular signaling targets, nuclear and epigenetic proteins, and other targets. Assay Ready Kits include all necessary reagents to run functional or binding whole-cell assays in just a few hours, including frozen, RTU pre-validated cells, optimized detection reagents, and media, 96-well plates, and detailed protocols.
Need continuous culture cell lines in an assay kit format? Consider complete cell-based assay kits that include the cell line, culture reagents for maintaining the cells in continuous culture, and detection reagents for running the assay. Learn more about Cell Line Assay Kits.
