eXpress Assay Kits

Discovery Phase Cell-Based Assays for Determining Proof-of-concept, MOA Confirmation, and Rank-ordering Studies

eXpress Assay kits developed by Eurofins DiscoverX^® are ready-to-use (RTU) cell-based assay kits for functional mechanism of action (MOA) or binding assay for drug discovery target validation, screening and hit ID, and lead optimization applications.

Each assay kit includes RTU cryopreserved cells, optimized assay reagents, plates, and a detailed assay protocol to ensure robust and reliable performance every time. By eliminating lengthy, time-consuming, and expensive cell culture steps, eXpress assay kits enable you to screen your small molecule or biologic therapeutics and generate accurate, precise, and reproducible functional data in just a few hours.

Eurofins DiscoverX offers over 1,000 target-specific eXpress assay kits for a broad range of target classes, including GPCRs, kinases, cytokine/interleukin receptors, checkpoint receptors, NHRs, epigenetic proteins, and more. The homogeneous assay kit format allows you to detect agonists, antagonists, and allosteric modulators. Their chemiluminescent read-outs can be read on any standard benchtop luminometer to provide fast and reliable results. Simply thaw, plate, and run the assay! Minimize assay development time and eliminate the need for cell culture.

eXpress Assay Kits are automation friendly and intended for in vitro research use only. These kits are not suitable for lot release applications. Refer to the bioassay format for potency testing in lot release for biologic therapeutics.
