CD23 PE

CD23 is a 45-kDa type II membrane glycoprotein, also known as the low-affinity IgE receptor (FcεRII), BLAST-2, Ly-42, or B6. As a member of the immunoglobulin superfamily, it is primarily expressed on conventional B cells and follicular dendritic cells, and can also be detected on monocytes, macrophages, eosinophils, platelets, and some dendritic cell subsets. CD23 plays an important role in regulating IgE homeostasis; elevated IgE levels can trigger CD23-mediated downregulation of IgE secretion.
