الوصف: A, B: AGS cells were pulsed with RBD for 30 mins or 3 hours, labelled with lysotracker in the last 15 minutes of pulse and imaged live at high resolution. Images are shown in A and quantification of Manders’ co-occurrence coefficient is shown in B. RBD is colocalized with Lysotracker positive compartments. With increase in time more RBD is associated with Lysostracker (p-value < e-06) and more Lysotracker positive compartments have RBD (p-value < e-06). Each condition has >12 cells. Dashed white line in A represents approximate cell boundary. C: Schematic describing the experimental protocol for estimating the pH of endosomes by ratiometric measurements using pH-sensitive (FITC) and pH-insensitive (TMR) dextran. D-F: AGS cells were pulsed with FITC and TMR dextran for 2 hours, chased for 1 hour with BafA1 200nM/400nM, NH 4 Cl 30mM or control and imaged live. Endosomal pH is increased upon addition of acidification inhibitors (p-values < e-118 for BafA1 200nM, < e-122 for BafA1 400nM, < e-223 for NH 4 Cl). Images along with pH maps are shown in D (and in S4C) and quantification in E (and in S4D). Enlarged regions of pH maps indicated by white boxes are shown in F. Box plot in E represents the distribution of medians of each repeat which is denoted by red dots. Violin plot indicates all the data points from repeats. Colour bar in F corresponds to the estimated endosomal pH. Control 1 is 0.2% DMSO, Control 2 is 0.4% DMSO and Control 3 is 0% DMSO. Number of repeats ≥ 3 for each treatment and each repeat has >80 cells. Scale bar: 20μm (A) and 40μm (D).
