Flow cytometric analyses of IL-3Rα chain.

Percentages of positive cells (A) and mean fluorescence intensity (MFI; B), in leukemic blasts derived from 79 patients with AML, 25 patients with B-ALL, and 7 patients with T-ALL, and from normal HPCs. Results are expressed in terms of the number of patients displaying a given range of expression of IL-Rα, either as a percentage of positive cells or of MFI.
