Construction and characterization of the MetRS mutant-based labeling system. A Scheme of the MetRS* expression plasmid PB-MetRS*. B Sodium dodecyl sulfate-polyacrylamide gel electrophoresis for the separation of cellular proteins of RD cells (lanes 1 and 2) and RD-MetRS* cells (lanes 3 and 4) cultured with or without ANL. The gel was stained with DBCO-AF647, and fluorescent signals were detected. C Wild-type RD cells and RD-MetRS* cells cultured with or without ANL were stained with DBCO-AF647 and observed under microscopy. Scale bar: 50 μm
