CD46 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Membrane Cofactor Protein (MCP) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Membrane Cofactor Protein (MCP) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

AHUS2; antigen identified by monoclonal antibody TRA-2-10; CD46 antigen, complement regulatory protein; CD46 molecule, complement regulatory protein; complement membrane cofactor protein; MCP; measles virus receptor; membrane cofactor protein; membrane cofactor protein (CD46, trophoblast-lymphocyte cross-reactive antigen) ; MIC10; TLX; TRA2.10; trophoblast leucocyte common antigen; trophoblast leukocyte common antigen; trophoblast-lymphocyte cross-reactive antigen.

Acts as a cofactor for complement factor I, a serine protease which protects autologous cells against complement-mediated injury by cleaving C3b and C4b deposited on host tissue. May be involved in the fusion of the spermatozoa with the oocyte during fertilization. Also acts as a costimulatory factor for T-cells which induces the differentiation of CD4+ into T-regulatory 1 cells. T-regulatory 1 cells suppress immune responses by secreting interleukin-10, and therefore are thought to prevent autoimmunity.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Membrane Cofactor Protein (MCP) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Membrane Cofactor Protein (MCP) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Membrane Cofactor Protein (MCP), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Membrane Cofactor Protein (MCP) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
