Labelling of Cells Engaged in DNA Synthesis: Autoradiography and BrdU Staining

  • Department of Medical Biochemistry
The cell cycle is divided in four phases: G1 phase, S phase (DNA-synthesis), G2 phase (together termed interphase) and M phase (mitosis). Cells that have ceased proliferation enter a state of quiescence called G0. M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's chromosomes are divided between the two daughter cells, and cytokinesis, in which the cell's cytoplasm divides in half forming distinct new cells. It is often necessary to evaluate the proportion of DNA-replicating nuclei (S-phase cells) in a given population of cells. Classical methods for detection of cells in the S phase use incorporation of modified nucleosides, followed by direct visualisation of the DNA -replicating cells
