The PathHunter TIM3/TIM3 Dimerization cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) targeting receptor-receptor interaction. This cell line enables assessment of 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. This stable modified cell line is provided as two vials of cryopreserved cells.
