WebCertain flow cytometry data analysis softwares are equipped with automated gating options for PI-stained cells. Additionally, one may consider using controls to arrest cells in certain phases of the cell cycle, such as using a Thymidine block (G1/S), serum starvation (G0/G1) or Nocodazole (G2/M) to establish gating. WebIn this way the distribution of cells in the phases of cell cycle could be determined and the movement of labeled cells through the phases of the cycle could be analyzed. Experiments in which the cell cycle distribution was studied at 4-h intervals after treatment showed the following: (1) Irradiation (4 Gy X rays) causes the expected G 2 block ...
