I am interested in purchasing PromoCell Human Mononuclear Cells (C-12907). Could you please let me know whether you have tested them for platelet contamination? If yes which markers / procedure have you tried?

During the isolation of our Human Mononuclear Cells (hMNC) we first of all pay attention to thoroughly discard the platelet-containing fraction before we aspirate the MNC containing-interphase of the Ficoll gradient. The harvested MNC fraction is then subjected to several washing steps to remove potential remaining platelets. Finally the cell preparations are verified by microscopy to be largely free of platelet contamination.
