Our Human CD32/FCGR2b/c ELISA Kit is a sandwich ELISA intended for the quantitative determination of human CD32 in cell culture supernates, serum and plasma (heparin, EDTA).
CD32 is a surface receptor protein and part of a large population of B cell co-receptors, which act to modulate signaling. It has a low-affinity for IgG antibodies and down-regulates antibody production in the presence of IgG. This feedback loops essentially lowers the production of IgG produced by B cells when there is a surplus in the body.
