Human CD markers chart

List and summary of all human CD antigens from CD1a to CD371.

The cluster of differentiation (CD) is a nomenclature system that identifies and classifies antigens found on the cell surface of leukocytes. Adopted in 1982, the Human Cell Differentiation Molecules organization continues to hold HLDA conferences to maintain and develop the list of known CD markers.

Under the CD system, antigens that are well characterized are assigned an arbitrary number (eg CD1, CD2, etc.). In contrast, molecules recognized by just one monoclonal antibody have the provisional designation 'CDw' (eg CDw50). Lower class letters indicate larger molecules with a chain in common (eg CD1a or CD1d). Physiologically, CD molecules do not belong to any particular class, with functions ranging from cell surface receptors to adhesion molecules. The CD molecule naming convention has expanded to cover different species (eg, mice) and other cell types.
