Human FcgR2B (Fc Fragment Of IgG Low Affinity IIb, Receptor) Microsample ELISA Kit

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 Human FcgR2B. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human FcgR2B. 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 Human FcgR2B, 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 Human FcgR2B in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 15.63-1000 pg/mL. Sensitivity: 6.4 pg/mL. Assay Type: Sandwich. Standard: 1000 pg/mL. Sample Type: sserum, plasma, tissue homogenates, cell lysates and other biological fluids. Assay duration: 3.5h. Protein Function: Receptor for the Fc region of complexed or aggregated immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B-cells. Binding to this receptor results in down-modulation of previous state of cell activation triggered via antigen receptors on B-cells (BCR), T-cells (TCR) or via another Fc receptor. Isoform IIB1 fails to mediate endocytosis or phagocytosis. Isoform IIB2 does not trigger phagocytosis [The Uniprot Consortium]
