  • Publication number: 20040180378
    Abstract: The invention is directed to polypeptides having a fluorescent activity, e.g., an auto-fluorescent activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. The polypeptides of the invention can be used as noninvasive fluorescent markers in living cells and intact organs and animals. The polypeptides of the invention can be used as, e.g., in vivo markers/tracers of gene expression and protein localization, activity indicators, fluorescent resonance energy transfer (FRET) markers, cell lineage markers/tracers, reporters of gene expression and as markers/tracers in protein-protein interactions.
