Overview

CD23 is a protein encoded by the FCER2 gene which is approximately 36, 4 kDa. CD23 is localised to the cell membrane. It is involved in cytokine signalling in immune system, notch2 activation, transmission of signals to the nucleus and B-cell development pathways. It is a B-cell specific antigen and a low-affinity receptor for IgE. It has essential roles in B-cell growth and differentiation, and the regulation of IgE production. It can also exists in a soluble secreted form which functions as a potent mitogenic growth factor. CD23 is expressed in the blood, lymph nodes and spleen. Mutations in the FCER2 gene may result in chronic conjunctivitis. STJ96951 was developed from clone 1E9 and was affinity-purified from mouse ascites by affinity-chromatography using specific immunogen. This primary antibody detects endogenous CD23 proteins.
