FACS analysis for the presence of human globin chains in the red cells of β-thalassemic mice.

Red cells from strains A, B, and C (panels A-C) were stained for the presence of hγ-globin chains while red cells from strain D (panel D) were stained for the presence of hβ-globin chains. Histograms show the number of cells (x-axis), the PE fluorescence (y-axis) for each antibody stain, and the mean (x) fluorescence intensity value of the main population of positively staining cells.
