The PathHunter Bevacizumab Bioassay HS Kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay asseses ligand (e.g. IL-10) based on activation of KDR/KDR Kinase activity via detection of Dimerization. The included cell line overexpresses ProLink-tagged KDR/KDR and EA-tagged . Activation of KDR/KDR stimulates the recruitment of and produces EFC signal.This assay has been optimized and qualified with Avastin® (not supplied in the bioassay kit). Avastin® is a registered trademark of Genentech, 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.
