This Monoclonal Antibody 2E1 recognizes the three isoforms of the Fc-gamma RII designated as A, B and C. Monocytes carry all forms of Fc-gamma RII, Neutrophils carry Fc-gamma RIIA and Fc-gamma RIIC. Fc-gamma RIIB is expressed by B lymphocytes and mast cells.
FACS: 10 μL stock solution to label 10^6 cells. Immunohistochemistry on Frozen Sections: 2 μg/mL (1/200). ELISA. Immunoprecipitation. Suggested Positive Control: Human tonsil. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Protocole

Stockage commentaire
Store the antibody at 2-8 °C before opening. DO NOT FREEZE! This product is stable at 2-8 °C as an undiluted liquid. For extended storage after reconstitution, add glycerol to a final concentration of 50% and store at -20 °C. Freezing alkaline phosphatase conjugates without glycerol will result in a substantial loss of enzymatic activity.

Sujet
CD32 is a receptor for the Fc region of complexed or aggregated immunoglobulins gamma. This is a low affinity receptor. It is 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 downmodulation of previous state of cell activation triggered via antigen receptors on B cells (BCR), T cells (TCR) or via another Fc receptor.Synonyms: CDw32, FCG2, FCGR2A, FCGR2A1, Fc-gamma RII-a, Fc-gamma-RIIa, IGFR2, IgG Fc receptor II, Low affinity immunoglobulin gamma Fc region receptor II
