CD7
Clone: C21-Q
Cat#: DB 114
CD7 antigen  is a cell surface glycoprotein expressed on the surface of immature and mature T cells, and natural killer cells. While its precise function is not known, there is recent suggestion that the molecule functions as an Fc receptor for IgM. CD7 is the most consistently expressed T cell antigen in lymphoblastic lymphomas and  leukaemias, and is therefore a useful marker in identification of such neoplastic proliferations.
