Confocal microscopy on immunofluorescently detected Beclin-1 in cytospin-isolated human white blood cells using Rabbit antibody to Beclin-1: whole serum (R-141-100) at a dilution of 1: 200, incubated for 1 h at room temperature. The cells were double-stained for Beclin 1 appearing in red and Myeloperoxidase appearing in green. The cells were counter stained with Hoechst Dye (blue colour). Here, the merged picture is presented.
