Average amplitude, width, and time delay of oscillation peaks and their variance, c11 = 0.139. (A–D) Average peak-to-trough amplitude and peak width of the first five p53 and MDM2 oscillation peaks and (E) average delay between P53 and MDM2 peaks in 100 cells shown with their standard errors. (F–J) The distribution of peak-to-trough amplitude, peak width, and delay divided by the mean value in logarithmic scale. Solid line: Log-normal probability density function with mean = 0 and standard deviation = 0.21(F), 0.08(G), 0.23(H), 0.07(I), 0.11(J).
