A549 cells express FLAG-GFP and DcsE tagged with FLAG and GFP. (a) GFP in FLAG-GFP transfected A549 cells (negative control) indicates expression of GFP-FLAG and more diffused protein. (b) GFP in DcsE-FLAG-GFP transfected A549 cells indicates more punctate expression of DcsE-FLAG-GFP. Light microscopy (LM), Green Fluorescent Protein (GFP). Scale bar is 100 µm.
