Invitrogen™ CD23 Recombinant Rabbit Monoclonal Antibody (007), FITC

Description

Preparation: This antibody was obtained from a rabbit immunized with purified, recombinant Mouse CD23 (Glu51-Pro331) and conjugated with FITC under optimum conditions, the unreacted FITC was removed. Storage: This antibody can be stored at 2C-8C for twelve months without detectable loss of activity. Protected from prolonged exposure to light. Do not freeze! Sodium azide is toxic to cells and should be disposed of properly. Flush with large volumes of water during disposal.

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.
