Supplementary Figure 8: 3D Exchange-PAINT imaging of PMP70 and catalase in A431 cells.
From: Modified aptamers enable quantitative sub-10-nm cellular DNA-PAINT imaging
(a) Exchange PAINT image of PMP70 (cyan) labeled with primary and secondary antibodies and catalase (magenta) targeted using a SOMAmer reagent. (b, c) Zoom-ins into regions highlighted in (a). Exchange-PAINT imaging shows peroxisomal membrane protein PMP70 surrounding catalase which is located inside peroxisomes Scale bars: 2 µm (a), 500 nm (b-c).
