Flow cytometric Density plot representation of platelets from Thrombocytopenic and normal horses. The two upper rows display the set of panels (FSC × FL1 plots of platelets) from two healthy horses while the two lower rows display the set of panels (FSC × FL1 plots of platelets) from two thrombocytopenic horses. The corresponding density plot (FSC × FL1) within the gates are shown in the columns. No gate (external left column). Gate R1 (internal left column. Gate R2 (internal right column). Gate R3 (external right column).
