Insoluble proteins accumulate in the nonquiescent population of postmitotic yeast. (A) Postmitotic cultures that had just entered stationary phase (young) or chronologically aged in stationary phase for 48 h (aged) were separated by Percoll gradient centrifugation into quiescent (Q) and nonquiescent (NQ) populations. (B) Young cells, aged Q, and aged NQ populations were harvested and insoluble protein extracted from a standard number of cells. SDS-insoluble protein from 8 × 107 cells was loaded in each lane.
