Fig. 6. Live imaging of SNAP and Halo-tagged glucagon-like peptide-1 receptor (GLP1R). (A–C) Widefield imaging and line plot intensity profiles of AD293 cells expressing SNAP-GLP1R labelled with BG-JF₅₄₉, BG-Sulfo549, BG-JF₆₄₆, or BG-Sulfo646, and Hoechst33342 staining. (D–F) Same as for A–C, but AD293 cells expressing Halo-GLP1R and labelled with the corresponding CA dyes. Scale bar = 20 μm.
