The ability of non-invasive monitoring of deep-tissue developmental, metabolic, and pathogenic processes will advance modern biotechnology. Imaging of live mammals using fluorescent probes is more feasible within a “near-infrared optical window” (NIRW). Here we report a phytochrome-based near infra-red fluorescent protein (iRFP) with the excitation/emission maxima at 690/713 nm. Bright fluorescence in a living mouse proved iRFP to be a superior probe for non-invasive imaging of internal mammalian tissues. Its high intracellular stability, low cytotoxicity, and lack of the requirement to add external biliverdin-chromophore makes iRFP as easy to use as conventional GFP-like proteins. Compared to earlier phytochrome-derived fluorescent probes, the iRFP protein has better in vitro characteristics and performs well in cells and in vivo, having greater effective brightness and photostability. Compared to the far-red GFP-like proteins, iRFP has substantially higher signal to background ratio in a mouse model owing to its infra-red shifted spectra.
