The PathHunter Tocilizumab Bioassay kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay assesses ligand (e.g. IL-6) induced dimerization of IL-6ST and IL-6R. receptors. This product uses EFC technology. The cell line included overexpresses IL-6ST target protein fused to PK alongside IL-6R target protein fused to EA. Upon ligand-induced dimerization of IL-6ST and IL-6R, detectable EFC signal is produced. Bioassay 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.
