Fig. 3.
A graphical output of an experiment utilizing 17 biosensors. SK-N-BE(2) biosensor-expressing cells were exposed to either vehicle, ouabain, or phorbol myristate acetate (PMA). Each tile represents a heatmap of a time-dependent plot of the relative changes in FRET ratio of each sensor within the dynamic range observed for that sensor throughout the experiment (fraction saturation) (see Note 8)
