Multi-color imaging of microtubule and mitochondria. a Two-color super-resolution images of microtubule (green) and mitochondria (red). The image was acquired from z = 0–500 nm. b Zoom-in image of the yellow box in (a). c-d Cross-sectional images for white lines of (b). e-h Maximum intensity projection images for different z-regions of (b). i Zoom-in image of mitochondria of the blue box in (a). j Optical z-axis sectional image in the range of z = 0 nm to 150 nm in (i). k Cross-sectional image for white line of (i). In the images of (c), (d), and (k), the z-direction is aligned to the vertical direction
