Description

Rat Monoclonal Antibody

Description: The B3B4 monoclonal antibody reacts with mouse CD23, a 45 kDa type II transmembrane glycoprotein. CD23 is expressed on resting conventional B cells, and its expression is modulated upon B-cell activation. B-1 cell lineage (CD5+ B cells) does not express CD23. Soluble forms of the antigen have been reported to be biologically active. CD23 is a low affinity receptor for IgE and is thought to play a role in the regulation of IgE response and B-cell activation. CD21 is thought to bind to CD23. This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer. Applications Tested: This eBio4KB128 antibody has been tested by flow cytometric analysis of mouse splenocytes. This may be used at less than or equal to 0.4 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest Master mixes.

CD23 is a 45 kDa glycoprotein that serves as a low-affinity receptor for IgE, playing a crucial role in regulating IgE responses and B cell activation. It is expressed on mature B cells, mantle zone B cells, follicular dendritic cells, and at lower levels on T cells, NK cells, Langerhans cells, and platelets. CD23 expression is upregulated upon B cell activation, and its soluble forms are biologically active, acting as potent mitogenic factors. CD23 is strongly expressed on Epstein-Barr virus (EBV)-transformed B lymphoblasts and is present on a subpopulation of freshly isolated peripheral blood and tonsil B cells. It is also detected in neoplastic cells from cases of B cell chronic lymphocytic leukemia and some centroblastic/centrocytic lymphomas. Functionally, CD23 is involved in B cell growth, differentiation, and IgE production. It interacts with CD21 and the alpha subunits of CD11b and CD11c, further influencing immune responses. Diseases associated with CD23 dysfunction include chronic conjunctivitis and chronic lymphocytic leukemia, highlighting its importance in both normal immune function and disease states. This makes CD23 a valuable target for antibody customers interested in B-cell-related research and diagnostics.
