The fluorescence units are partition units per cell, which are calculated according to Teng et al. (28).

Partition unit can be a dimer or an oligomer if the protein dimerizes or oligomerizes; 260 cell division events were used for the estimation.

^∗SD of cell autofluorescence is comparable to that of signal fluorescence, making the error bars large.
