Fig. 1.
Two-color flow cytometry analysis of follicular lymphoma cells.
Scatterplots by 2-color staining with (A) anti-CD20–FITC and anti–κ light chain–PE or with (B) anti–κ light chain–FITC and anti-CD59–PE from a typical tumor sample were shown. Mean channel fluorescence of CD20 and CD59 (similar in CD46 and CD55) were determined in κ light chain- (or λ light chain- in other cases) positive cells as gated in panels A and B.
