Cd markers , cd : cluster of differentiation 標志,分化抗原標志
Precursor cells from different lineages express different subsets of surface molecules , many of which are now difined by cluster of differentiation ( cd ) antigens . cd antigens associated with the plasma membranes of leukocytes may be molecules involved in a variety of functions 蛋白芯片可以將蛋白質(zhì)以陣列的方式固定在經(jīng)化學(xué)或生物酶處理的表面上,也可將受體蛋白、抗體等固定在表面上,未知分子可以利用與芯片不同位點親和力來分析。
百科解釋
The cluster of differentiation (cluster of designation) (often abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules providing targets for immunophenotyping of cells. Physiologically, CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell.
