The PathHunter TGFBR1/ACVR2B Dimerization eXpress kit provides an easy-to-use cell based assay to study drug candidates (small molecules or biologics) targeting receptor-receptor interaction. This kit assesses ligand (e.g. GDF-11) induced dimerization of TGFBR1/ACVR2B receptors. This product uses EFC technology. The cell line included overexpresses ACVR2B target protein fused to PK alongside TGFBR1 target protein fused to EA. Upon ligand-induced dimerization of TGFBR1/ACVR2B, detectable EFC signal is produced. 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.
