An automated system for cell cycle analysis is described in which synchronous populations of greater than 95% mitotic cells can be selected and subcultured without resorting to inhibitors or altered media. Selection of mitotic cells from roller bottle cultures generates synchronous populations of up to 5 × 10 7 cells, as often as every 30 min, under conditions of constant temperature. A detailed analysis of the temporal pattern of DNA synthesis in the S phase of several Chinese hamster cells is presented. Several potential artefacts and uncertainties regarding the cell cycle blockage point in S phase synchronization are discussed.
