The cluster of differentiation (CD) antigens is a protocol used for the identification and investigation of cell surface molecules present on leukocytes. Some CD proteins often act as cell-cell or cell-matrix adhesion molecules, cytokine receptors, ion pores, or nutrient transporters. Some CD proteins play a role in cell signaling, other CD molecules mediate cell adhesion. Cell adhesion is a dynamic process by which cells form contacts with each other or with their substratum through specialized protein complexes. Cell-cell adhesion helps shape tissue organization during morphogenesis and preserves tissue cohesion in post-developmental life. MCE offers a variety of recombination CD antigens related to cell adhesion research.
