The fluorescent microscopy image of the HEK293T cells transfected with wild type cystic fibrosis transmembrane conductance regulator (CFTR) tagged with enhanced yellow fluorescent protein (EYFP). Nuclei were stained with DAPI (blue). This image shows that CFTR tagged with EYFP in or near membrane (in collaboration with Dr. Estelle Cormet-Boyaka and Albert Tousson).
