| dc.description.abstract | Transient inactivation of the cdc25(+) gene product by manipulation of the culture temperature for cdc25-22 cells is the most commonly exploited approach to mitotic synchronization in fission yeast. Because Cdc25 removes the inhibitory phosphate placed on Cdk1 by Wee1, inactivation of Cdc25 arrests cells at the G2/M boundary. Incubation at the restrictive temperature of 36°C for just over one generation time forces all cells in the culture to accumulate at the G2/M boundary. Restoration of Cdc25 function via a return to the permissive temperature or chemical inhibition of Wee1 activity at 36°C can then promote a highly synchronous wave of cell division throughout the culture. These approaches can be performed on any scale and thus support simultaneous assessment of numerous events within a single culture. After describing this simple and widely applicable procedure, we discuss frequently overlooked issues that can have a considerable impact on the interpretation of data from cdc25-22 induction-synchronized cultures. | |
