The CD5 antigen is present on approximately 70% of normal peripheral blood lymphocytes and >90% of all T-lymphocytes. T-lymphocytes in the thymus stain weakly while peripheral T-cells stain strongly. Monocytes, granulocytes and NK cells are not stained (1). Anti-CD5 also reacts with a distinct subset normal B-lymphocytes, occasional cells in B-lymphocyte areas of spleen and lymph node, and most Ig+ B-chronic lymphoblastic leukemia (CLL) cells. The CD5 antigen has also been shown to be present on some lymphomas.
