Fig. 1.
Sickle cell density distributions before and after isolation of dense cells.
The 3 panels on the left represent the red cell density distributions for 3 patients (H7-1, H7-2, and H7-3) prior to isolation of dense cells. On the right are shown the corresponding density distributions of the biotin-labeled HDE cells at the time of re-infusion. The density range for each fraction is shown in the upper left panel.
