CD3 - Cluster of differentiation 3

CD3 antigen can be found bound to the membranes of all mature T-cells and in virtually no other cell type. This high specificity, combined with its presence at all stages of T-cell development makes it a useful T-cell marker for IHC tissue sections. The antigen is also present in almost all T-cell lymphomas and leukaemias, allowing their differentiation from similar B-cell and myeloid neoplasms.
