CD4 FITC - CD62L PE

- +

CD4 is used in the identification of human helper/inducer T cells expressing the 60,000 M.W. surface antigen (HLA class II reactive). CD4 is present in low density on monocytes._x000B__x000B_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, _x000B_LECAM-1, or gp90MEL-14. This antibody to L selectin blocks greater than 95% of lymphocyte adhesion to peripheral lymph node high endothelial venules. _x000B__x000B__x000B_
