The PathHunter TIM3/TIM3 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 induced dimerization of TIM3/TIM3 receptors. This product uses EFC technology. The cell line included overexpresses TIM3 target protein fused to PK alongside TIM3 target protein fused to EA. Upon ligand-induced dimerization of TIM3/TIM3 , 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, control agonist, detection reagent, and assay plates.
