CD Antigens

CD Antigens

The Cluster of Differentiation (CD) antigens indicates a defined subset of cellular surface receptors (epitopes) that identify cell type and stage of differentiation, and which are recognized by antibodies. They are protocols used for the identification and investigation of cell surface molecules providing targets for immune-phenotyping of cells.CD antigens participate in immune reaction as receptors for cell communication (e.g. adherence molecules, antigen recognizing receptors). The expression of CD antigens is influenced by cytokines, such as binding of ligands to CD antigens which has shown to modulate the expression of cytokines. CD antigens have been shown to be identical with receptors of cytokines such as CD25 (TAC antigen). Some CD proteins do not play a role in cell signaling, but have other functions, such as cell adhesion. CD antigens are used widely for research, immunotherapy, tumor and drug target.

KRISHGEN offers a wide range of ELISAs for estimation of CD antigens in different species.
