Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate ALCAM in samples. An antibody specific for ALCAM has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyALCAM present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for ALCAM is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of ALCAM bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:ALCAM/CD166 is a member of the immunoglobulin gene superfamily belonging to a subgroup with five extracellular immunoglobulin-like domains(VVC2C2C2), which includes MCAM/CD146/MUC18 and B-CAM/Lutheran. These molecules are involved in the development and maintenance of tissue architecture, neurogenesis, hematopoiesis, immune responses and tumor progression. ALCAM/CD166 mediates cell-cell clustering through homophilic (ALCAM-ALCAM) and heterophilic (ALCAM-CD6) interactions. Its pattern of expression in human tissues and cells is broad and includes epithelia, neurons, lymphoid and myeloid cells, hematopoietic and mesenchymal stem cells. The relevance of the engagement of the heterophilic pair CD166-CD6 for optimal activation of T cells has been recently demonstrated.
