Fluorescent microscopy of bacteriorhodopsin coexpressed with sf-GFP:. Microscopy pictures were taken with a Zeiss Elyra PS. Peroxisomes were labeled with GFP-PTS1 (green). The green fluorescent spots (on the right) shows a typical peroxisomal shape. The signal for the membrane marked bacteriorhodopsin is shown in red (on the left). Both signals show colocalization when merged (middle), which indicates that the protein gets integrated into the membrane.
