Figure Lengend Snippet: A. Three-colour high resolution confocal fluorescence imaging of endogenous HaloTag-Sec23A RPE1 cells dyed with HaloTag JFX650 ligand (green) and stained with antibodies directed against Sec16 (orange) and 𝛽-COP (purple). B. Quantitative data highlighting the relative distribution of COPII (HaloTag-Sec23A) and transitional ER (Sec16A). Left panel: Violin plots of the distance between centroids of endogenous HaloTag-Sec23A puncta from immunostained Sec16 and 𝛽-COP. Extracted from the three-color high resolution confocal fluorescence imaging as exampled in A. For Sec16, n = 5819, from ≥10 cells, across 3 experimental repeats. For 𝛽-COP, n = 4950, from ≥10 cells, across 4 experimental repeats. Right panel: Averaged linescans of Sec16 (orange) and HaloTag-Sec23A (green), extracted from two-colour super resolution STED imaging and fitted from 50 structures across 2 cells over 1 experimental repeat. Standard error is shown by the dotted lines. The intensity values were normalized for display purposes. C. Three-color high resolution confocal fluorescence imaging of endogenous HaloTag-Sec23A RPE1 cells dyed with HaloTag JFX650 ligand (green) and stained with antibodies directed against ERGIC-53 (cyan) and 𝛽-COP (purple). D. Two-colour super resolution STED imaging of endogenous SNAP-tag-ERGIC-53 RPE1 cells stained with antibodies directed against 𝛽-COP (purple) and SNAP-tag-ERGIC-53 dyed with JFX650-SNAP-tag ligand (cyan) Scale bar: A,C overviews: 1 µm, insets: 200 nm, D: 100 nm

Figure Lengend Snippet: Normalized reflectance spectral responses with correlation values when illuminating the polymer reference with lamps B and D from Fig. and captured with different sensors. Spectrometer measurements were performed with a fibre optic orthogonal to the polymer reference from a 5 cm distance. The hyperspectral camera captures a scene of the polymer at approximately 72.5 degrees and 40.5 cm distance and uses a region of interest of 25 × 25 pixels. Note that captures taken at 90 ∘ and 0 ∘ would mean pointing the camera to a vertical wall and to the floor, respectively. These responses from the HS cameras are the mean spectral signatures of the 25 × 25 pixel polymer pixels with their corresponding standard deviations, shown with shaded colours between their corresponding means. The spectrometer uses 2055 bands and covers the 350–925 nm range. The HS linescan VNIR camera covers the 400–1000 nm spectral range and uses 369 bands. Finally, the HS snapshot NIR camera spectra ranges from 660–950 nm and includes 25 bands. The Pearson correlation is presented after the measured bands of each sensor are compared with the polymer reference response. The visible (VIS) spectra is illustrated with rainbow shading in the 380–740 nm range.
