The first left panels show an example of rendered particles created with the spot finder wizard using the signal from mRuby2. The second panels show an example of segmented cells (in green, purple, and violet) obtained through the cell finder wizard using the staining of cytoplasmic GAPDH. Phalloidin‐atto 390 signal, staining F‐actin, was used to find cell surface (represented in glass transparent color) and, finally, distance of each particle with respect to the cell cytoplasm, and surface was calculated. On the top, raw data are shown, while on the bottom, the rendering is shown. The last panel shows an example of cytoplasmic, surface‐associated, and extracellular particles in blue, yellow, and red, respectively. Scale bar = 4 μm.
