CD23 antibodies, human

Clone: M-L23.4 | Dilution: 1:50
CD23 is a 45 kDa type II transmembrane glycoprotein that belongs to the immunoglobulin family. It is expressed on most mature B cells, monocytes, follicular dendritic cells, and at low levels on T cells, Langerhans cells, eosinophils, and platelets. CD23 is thought to play a role in the regulation of B cell activation and IgE response. It is up-regulated upon B cell activation. The proteolytic cleavage of membrane CD23 can result in the release of soluble forms of the antigen (sCD23) with a reported biological activity.
