Form:Supplied as a liquid in PBS, pH 7.4, 1% BSA, 0.09% sodium azide. Labeled with Fluorescein Isothiocyanate Isomer 1 (FITC).
Specificity:Binds to the human CD39 cell surface antigen, an 80kD molecule expressed on peripheral blood B cells, monocytes and T cell clones. Weakly expressed on granulocytes. Expression is induced on T cells and increased on B cells as a late activation antigen. This antibody has been shown to block MHC independent target cell recognition by hapten- specific CTL.
