Urelumab ELISA Kit

Urelumab is a fully humanized agonistic monoclonal antibody targeting the CD137 receptor with potential immunostimulatory and antineoplastic activities. Urelumab specifically binds to and activates CD137-expressing immune cells, stimulating an immune response, in particular a cytotoxic T cell response, against tumor cells. Urelumab has been used in trials studying the treatment of Leukemia, Multiple Myeloma, Malignant Tumors, and Cancer-Solid Tumors and B-Cell Non-Hodgkin's Lymphoma. The antibody product was developed using Medarex's UltiMAb (R) technology and was the first UltiMAb-derived antibody in clinical development by Bristol-Myers Squibb under the December 2003 agreement with Medarex. In December 2008, enrolment was stopped for all urelumab studies following the occurrence of two hepatotoxicity-related deaths. Several years later, the clinical study on Urelumab was restarted. At present, the approval of the monoclonal antibody has not been disclosed in the relevant drug approval agency.

PRINCIPLE OF THE ASSAY This assay employs the quantitative indirect enzyme immunoassay technique. Recombinant Human CD137 has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any Urelumab present is bound by the immobilized protein. After washing away any unbound substances, a biotin-labeled Mouse Anti-Human IgG antibody is added to the wells. 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 proportion to the amount of Urelumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
