Description
PRINCIPLE OF THE ASSAY
This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human CD221 has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Cixutumumab in the sample competitively binds to the pre-coated protein with biotin-labeled Cixutumumab. 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 Cixutumumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
Applications
Used for the quantitative determination of Cixutumumab concentration in serum and plasma.

Background
Cixutumumab (IMC-A12) is a fully human IgG1 monoclonal antibody directed against the human insulin-like growth factor-1 receptor (IGF-1R) with potential antineoplastic activity for the treatment of solid tumors. This drug was developed by ImClone Systems, since acquired by Eli Lilly, using phage display technology from Dyax. Cixutumumab was well tolerated when used alone and in combination therapies, but its antitumor activity was low in the existing phase II clinical trials. An acceptable incidence of adverse effects supports further investigation of this drug, provided that it shows antitumor activity in combination with other drugs. Now, cixutumumab is involved in two cancer clinical trials, including esophageal cancer and breast cancer.
