short description

The Bioaim Human FcgRII BC ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of FcgRII BC in Human serum, plasma and cell culture media. An antibody specific for Human FcgRII BC was coated on a 96-well plate. Standards and samples are added to the wells and any FcgRII BC present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human FcgRII BC antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of FcgRII BC present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.

detection target

Fc fragment of IgG receptor IIb (FcgRIIBC)
Background: Receptors that recognize the Fc portion of IgG are divided into three groups designated Fc gamma RI, RII, and RIII, also known respectively as CD64, CD32, and CD16. In humans each group of receptors is encoded by 2 – 3 closely related genes designated A, B, and C. Fc gamma RI binds IgG with high affinity and functions during early immune responses. Fc gamma RII and RIII are low affinity receptors that recognize IgG as aggregates surrounding multivalent antigens during late immune responses. Different Fc receptors can function as activators, as inhibitors, or as decoy receptors. The inhibitory CD32B is expressed on B cells and myeloid dendritic cells. Ligation of CD32B on B cells downregulates antibody production and may, in some circumstances, promote apoptosis. Co-ligation of CD32B on dendritic cells inhibits maturation and blocks cell activation. CD32B may also be a target for monoclonal antibody therapy for malignancies.
