Optimization of HEK-293 T cell transfection with SARS-CoV-2-Mpro and the dark-to-bright GFP substrate. a Cells transfected with PR-Sub and CoV-2 Mpro under native microscopic light. b Visualization of cells transfected with PR-Sub under fluorescent microscope. c Visualization of cells transfected with PR-Sub and CoV-2 Mpro under fluorescent microscope. Co-transfection with both plasmids resulted in 28–34% GFP fluorescence
