title: Standardized shake-off to synchronize cultured CHO cells.
abstract: A protocol to obtain CHO cells synchronized in mitosis is described. The synchronized population contained hardly any S-phase cells as judged by the incorporation of 3H-TdR. In these cells a very low frequency of chromatid-type aberrations compared with chromosome-type aberrations was induced by X-rays at 1.5 h after the synchronization.
