DiscoverX PathHunter™ eXpress FGFR4-β-Klotho Functional Assay

The PathHunter™ eXpress FGFR4-β-Klotho Functional Assay provides an easy-to-use cell based assay to study drug candidates (small molecules or biologics) targeting RTKs. This kit assesses RTK activation via detection of activated FGFR4 and β-Klotho dimerization-induced SH2 domain protein recruitment. This product uses EFC technology. The included cells overexpress PK-tagged FGFR4 and an EA-tagged SH2 domain protein. It also overexpresses an untagged coreceptor, β-Klotho Upon ligand-induced receptor activation, SH2-EA recruitment leads to production of EFC signal. eXpress kits are a convenient, ready-to-use format which contains all materials needed to run the assay, including single-use vials of cryopreserved cells, cell plating media, detection reagent, and assay plates.
