CD23, also known as Fc epsilon RII, or FcεRII, is the "low-affinity" receptor for IgE. Unlike many of the antibody receptors, CD23 is a C-type lectin. It is found on mature B cells, activated macrophages, eosinophils, follicular dendritic cells, and platelets. CD23 is known to have a role of transportation in antibody feedback regulation. Antigens which enter the blood stream can be captured by antigen specific IgE antibodies. The IgE immune complexes that are formed bind to CD23 molecules on B cells, and are transported to the B cell follicles of the spleen. In flow cytometry, CD23 is helpful in the differentiation of chronic lymphocytic leukemia (CD23-positive) from mantle cell lymphoma (CD23-negative). CD23 can also be demonstrated in germinal centre follicular dendritic cells using immunohistochemistry but is minimally expressed by benign germinal center B cells.
IHC shows positive staining in paraffin-embedded human tonsil. Anti-CD23 antibody was used at 1/2000 dilution, followed by a Goat Anti-Rabbit IgG H&L (HRP) ready to use.
Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

Negative control: IHC shows negative staining in paraffin-embedded human colon. Anti-CD23 antibody was used at 1/2000 dilution, followed by a Goat Anti-Rabbit IgG H&L (HRP) ready to use. Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IF shows positive staining in paraffin-embedded human tonsil. Anti-CD23 antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
