The y-axis shows the percentage of Ph-positive cells in each graph. The x-axis for patients 1 through 10 is the number of days treated with IFN-α2b with or without ara-C. The x-axis for serial dilutions represents different mixtures of normal and Ph-positive cells: the expected percentage of Ph-positive nuclei is 98.2, 49.1, 12.3, 3.1, and 0.0 for specimens 1 through 5, respectively. Patients 2 and 7 had atypical D-FISH patterns. Patient 6 had a masked Ph chromosome.
