CD16/32 Antibody – Rat Monoclonal

FCGR2B: a transmembrane receptor for the Fc region of complexed or aggregated immunoglobulin gamma (IgG). 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, T cells or via another Fc receptor. Three splice-variant isoforms have been observed.
