The invention relates to a method of synchronizing a population of somatic cells in G1 for purposes of preparing the cells for nuclear transfer or nuclear transplantation by using mechanical shake-off and selection of mitotic doublet cells. This method may further comprise cooling of the cells or other means of synchronizing the cells in G1 phase for longer periods of time. The invention also relates to the use of a synchronized population of rapidly dividing somatic cells obtained by these methods as a source of donor nuclei or chromatin for use in nuclear transfer or nuclear transplantation.

Why it's free to use
- Filed October 13, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
