Description
PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human EGFR has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Panitumumab in the sample competitively binds to the pre-coated protein with biotin-labeled Panitumumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Panitumumab bound in the initial step. The color development is stopped and the intensity of the color is measured.

Background
Panitumumab, formerly ABX-EGF, is a fully human monoclonal antibody (mAb) specific to the epidermal growth factor receptor (also known as EGF receptor, EGFR, ErbB-1 and HER1 in humans). Panitumumab was originally developed by Abgenix using Abgenix's XenoMouse platform technology, in which engineered mice were utilized to produce human antibodies. This methodology is based on inactivating the mouse immunoglobulin genes that are replaced by a megabase gene containing the human heavy and κ chains. The result is the generation of fully human antibodies that do not contain murine portions of the IgG molecule as chimeric antibodies do. This property avoids the formation of human antimouse antibodies, which may result in more frequent hypersensitivity reactions and shorter half-life.
