Abstract
This chapter provides a method for quantitative single cell analysis to track the transition of single cells from G2, indicated by high cyclin B1 levels, to G1 polyploidy phase (G1(p)), indicated by low cyclin B1 levels, in a 4n population. The cell tracking methodology described provides a fluorescence fingerprint suitable for deriving G2/M or G2/G1p transitions. Notably, during late G2 the absolute cyclin B1-eGFP reporter levels obtained were high and the switch-off point identifiable, with destruction rates of a similar order across all cell cycle routing avenues. The three principle parameters extracted were defined as (1) G2-to-G1(p) transition duration (tGFPoff); (2) rate of sensor destruction (kGFPoff), and (3) peak sensor expression (GFPpeak).
