KCl increases Fluo-4AM fluorescence intensity in HEK293.
(a) Image of HEKs loaded with Fluo-4AM grown on the P1M3DH calcium free solution. (b) Increased fluorescence intensity after hyperpolarising the cells with high potassium solution (140 mM KCl). (c) Randomly selected cells for labeling of ROIs. (d) Ratio of fluorescence intensity change (∆F/F) in cells labeled in C. (e) Mean of fluorescence change (∆F/F).
