Systematic characterization of maturation time of fluorescent proteins in living cells
Slow maturation time of fluorescent proteins limits accurate measurement of rapid gene expression dynamics and effectively reduces fluorescence signal in growing cells. We used high-precision time-lapse microscopy to characterize, at two different temperatures in E. coli, the maturation kinetics of...

Sumario: | Slow maturation time of fluorescent proteins limits accurate measurement of rapid gene expression dynamics and effectively reduces fluorescence signal in growing cells. We used high-precision time-lapse microscopy to characterize, at two different temperatures in E. coli, the maturation kinetics of 50 FPs that span the visible spectrum. We identified fast-maturing FPs that yield the highest signal-to-noise ratio and temporal resolution in individual growing cells. |
