Figure Lengend Snippet: Sample plating layout To aid in the differentiation of control reactions from sample reactions, designate a row within a plate to controls (top row), followed by samples. Cells within the control wells will not be used to screen biological samples. The IgG Positive control will receive both the anti-CD98 antibody, as well as the staining cocktail. Single color controls, in concert with the unstained control will provide preliminary guidance as to where to draw positive-event gates. The placements of these gates are later refined by the boundaries set by the fluorescence-minus-one controls. We separated healthy human control samples from biological human samples of interest. These healthy human controls can further refine the lower limits of positive-event gates, as it is hypothesized that healthy human controls lack or have minimal circulating autoantibodies.
