Fig. 9From: Designing, construction and characterization of genetically encoded FRET-based nanosensor for real time monitoring of lysine flux in living cellsLysine concentration change in the cytosol of yeast. S. cerevisiae/URA3 strain BY4742 expressing the sensor FLIPK. The graph indicates the emission intensity ratio (535/485 nm ratio) for a single yeast cell. Addition of 100 mM lysine (shown by arrow) increased the ratio by 2.0Back to article page
