Fig. 7. DNA content as measured by binding of propidium iodide. (A) Histogram of normal diploid pattern. In this display, the modal fluorescence of cells with 2n DNA (i.e., G1-phase) is about channel 200, whereas that of cells with 4n DNA (i.e., G2-phase) is about channel 400. Cells engaged in DNA synthesis (S-phase) are found between these two peaks. (B) Partial hydatidiform mole. The G1 peak of normal cells is seen at about channel 200, whereas the G1 peak of the aneuploid (triploid, or 3n) cell population is seen at about channel 300. The peak at about channel 600 represents the G2 peak of the aneuploid population (6n DNA).
