These were performed exactly as described previously (Selyunin and Mukhopadhyay, 2015 (link)). To summarize details of the microscope in this study, we used a sweptfield confocal microscope equipped with a four-line high-power laser launch and a 100× 1.45 NA oil immersion objective (Nikon). An iXon3 X3 DU897 electron-multiplying charge-coupled device camera (Andor Technology) was used for image capture. All images were captured as z stacks with 0.2-µm spacing between individual frames. Images depicted in the figures are maximum-intensity projections of the stacks.
All analyses were performed using ImageJ (National Institutes of Health) as described previously (Selyunin and Mukhopadhyay, 2015 (link)).
