Anti-Mouse CD23 (PE Conjugated)[B3B4], clone B3B4

CD23 is a 45 kD protein also known as low affinity IgE Fc receptor, FcepsilonRII, BLAST-2, Ly-42, or B6. It is a member of the Ig family, expressed on conventional B (but not B-1) cells and follicular dendritic cells. CD23 responds to high levels of IgE by downregulating IgE secretion. Protein function: Low-affinity receptor for immunoglobulin E (IgE) and CR2/CD21. Has essential roles in the regulation of IgE production and in the differentiation of B-cells (it is a B-cell-specific antigen). [The UniProt Consortium]
