This protocol provides a method for the synchronization of a monolayer culture of CHO cells in G1 using isoleucine deprivation. Since CHO cells can also be adapted to grow in suspension culture, this procedure can be used to obtain larger quantities of cells. When isoleucine is replaced, the cells resume growth and begin to enter S phase ~4 hours later. This method arrests almost 100% of the CHO cells in G1, and upon reversal, leads to rapid recovery of cell growth and very high cell viability. - [Read G1 Synchronization of CHO Cells by Isoleucine Deprivation Protocol]
