PHA activated human lymphocytes.
Recognizes the human CD39 cell surface antigen, a ~70-100 kD molecule expressed on peripheral blood B cells, T cells and monocytes, and weakly expressed by granulocytes. CD39 has intrinsic ecto-ATPase activity, and expression can be induced on T cells and increased on B cells, as a late activation antigen. Has been shown to block MHC independent target cell recognition by hapten-specific CTL.
