CD3 FITC - CD62L PE

The CD3 epitope is expressed on the epsilon chain of the CD3/T cell antigen receptor (TcR) complex. CD3 is expressed on 65-85% of thymocytes and has a mitogenic effect on peripheral blood T cells. Identification of human T cells expressing the 22-28,000 M. W. surface antigen. CD62L is the equivalent of the mouse MEL-14 with a molecular weight of 80 KDa. CD62L is on 60-75% of peripheral blood lymphocytes, Approximately 70-80% of T cells, 10% of thymocytes and most B cells. CD62L reacts with monocytes, granulocytes and a subset of NK cells. The selectins represent a family of adhesion molecules, expressed by leukocytes and endothelial cells that are involved in the regulation of leukocyte traffic. Human leukocyte L selectin is also called LAM-1, LECAM-1, or gp90MEL-14. This antibody to L selectin blocks greater than 95% of lymphocyte adhesion to peripheral lymph node high endothelial venules.
