Additional confocal microscopy images of GFP-tagged vPOIs of SARS-CoV-2 (a) Confocal microscopy images of ORF3a-GFP (left) and M-GFP (right) with SEC61B-V5-TurboID. SEC61B-V5- TurboID was visualized by Anti-V5 antibody (AF647-conjugated secondary antibody, Cy5 fluorescence channel). Pearson correlation values were calculated between different fluorescent channel images. BF: bright field, Scale bars: 10 μm. (b) Confocal microscopy images of co-expressed vPOI-GFP and vPOI-Flag. Flag-conjugated vPOIs (ORF3a, ORF6, ORF7b, M of SARS-CoV-2) were visualized by using Anti-Flag antibody (AF647-conjugated secondary antibody, Cy5 fluorescence channel) and GFP-conjugated vPOIs fluorescence was detected in GFP fluorescence channel. Pearson correlation values were calculated between different fluorescent channel images.
