The PathHunter Panitumumab Bioassay Kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay asseses ligand (e.g. FGF-19) based on activation of EGFR/ErbB2 Kinase activity via detection of SH2 Recruitment. The included cell line overexpresses ProLink-tagged EGFR/ErbB2 and EA-tagged . Activation of EGFR/ErbB2 stimulates the recruitment of and produces EFC signal.This assay has been optimized and qualified with Vectibix® (not supplied in the bioassay kit). Vectibix® is a registered trademark of Amgen Inc.. 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.
