| mitotic shake off method | <cell biology, procedure> A method of collecting cells in mitosis, so that the chromosomes can be examined and the karyotype determined. Many cultured cells round up during mitosis and so become less firmly attached to the culture substratum. Cells in mitosis thus can be removed into suspension by gentle shaking of the culture vessel, leaving the nonmitotic cells still attached. The number of cells that are in mitosis is usually increased by using a drug, such as colcemid that blocks mitosis at metaphase. (18 Nov 1997) |
