Purity：Purified by Protein G affinity chromatography.
Form：Supplied as a lyophilized powder in PBS, pH 7.2, 1% BSA, 0.09% sodium azide. Reconstitute with 1ml sterile ddH2O. Labeled with R. Phycoerythrin (RPE).
Specificity：Binds to the human CD39 cell surface antigen, a 70-100kD molecule expressed on peripheral blood B cells, monocytes and T cell clones. CD39 has intrinsic ecto-ATPase activity. 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.
