12、nuclear dye. The mean intensity of the nucleus is fairly constant during S-phase and the nuclear size increases During M-phase and early G1-phase the nuclear size decreases, resulting in higher mean intensity values. Cells with 2N DNA (G1-phase) and 4N DNA (G2-/M-phase) can be clearly distinguished.
