Human CD83 is a 40-50 kDa member of the Siglec (or sialic-acid-binding immunoglobulin-like lectin) family of transmembrane proteins. CD83 is a primary marker for dendritic cells. It is also found on B cells, neutrophils, monocytes and macrophages. Except for dendritic cells, CD83 expression is often transient. CD83 binds to sialic acids on target cells. Membrane CD83 promotes T cell proliferation, particularly of CD8+ cytotoxic T cells. Soluble CD83 is immunosuppressive and blocks T cell activation. On monocytes, CD83 is suggested to drive monocytes into a fibrocyte phenotype. A lack of membrane-expressed CD83 leads to an unusual IL-4/ IL-10 producing CD4+ T cell phenotype. - Protein. The extracellular domain of human CD83 (aa 20-131) is fused to the N-terminus of the Fc region of a mutant human IgG1. Source: CHO cells. Endotoxin content: <0.06EU/microg protein (LAL test; Lonza). Lyophilized from 0.2microm-filtered solution in PBS. Purity: >98% (SDS-PAGE).
