Cell phase: The phase in a cell cycle that corresponds to a defined DNA content range determined by flow cytometry measurements that includes G1 (gap phase 1), S phase (the DNA synthesis phase), and G2/M (the gap 2 and mitosis phases; here abbreviated G2). Different portions of S phase are obtained by dividing the cell cycle into seven DNA content windows based on the relative peak positions corresponding to the G1 and G2 cell cycle fractions. The G1 peak position is routinely set at "60" relative UV fluorescence, thus producing G2 peak values in the 116-120 range
PhaseDescriptionLabel
G1 Flow sorted, G1 phase corresponds to the first DNA content window G1
G1b Flow sorted, G1b phase corresponds to the second half of the first DNA content window G1b
G2 Flow sorted, G2 phase corresponds to the second DNA content window G2
S1 Flow sorted, S1 phase corresponds to the third DNA content window S1
S2 Flow sorted, S2 phase corresponds to the fourth DNA content window S2
S3 Flow sorted, S3 phase corresponds to the fifth DNA content window S3
S4 Flow sorted, S4 phase corresponds to the sixth DNA content window S4
