These images represent fluorescent monoclonal antibody data for CD19 and CD20, respectively. In each histogram, the peak to the left of the vertical line represents cells that are negative for the marker, and the peak to the right represents positive cells for the marker. This means that the percentage of cells in the gated population (lymphocytes) with CD19 cell surface antigens is 6.8%, and CD20-positive cells comprise 6.7%.
A CD5 analysis further confirmed that the B cell population was CD5-negative.
The B cell expression at this point is:
CD5=0%
CD19= 7%
CD20= 7%
