DescriptionRabbit monoclonal [EP888Y] to CD32B
SpecificityThis antibody has weak cross-reactivity with CD32A and CD32C. It detects weak signal in CD32A and CD32C over-expressed lysates at the dilution of 1/200 under the exposure time of 3 minutes, but detects strong band in CD32B over-expressed lysates at the dilution of 1:2000 under the exposure time of 15 seconds.

FunctionReceptor 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.
Tissue specificityIs the most broadly distributed Fc-gamma-receptor. Expressed in monocyte, neutrophils, macrophages, basophils, eosinophils, Langerhans cells, B-cells, platelets cells and placenta (endothelial cells). Not detected in natural killer cells.
Involvement in diseaseNote=A chromosomal aberration involving FCGR2B is found in a follicular lymphoma. Translocation t(1;22)(q22;q11). The translocation leads to the hyperexpression of the receptor. This may play a role in the tumor progression.
Sequence similaritiesContains 2 Ig-like C2-type (immunoglobulin-like) domains.
DomainContains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
Cellular localizationCell membrane.

Immunohistochemical staining of paraffin embedded human spleen with purified ab45143 at a working dilution of 1/1000. The secondary antibody used is ab97051, a goat anti-rabbit IgG (H&L) at a dilution of 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.
