Near-infrared fluorescent proteins for multicolor in vivo imaging
Near-infrared fluorescent proteins are in high demand for in vivo imaging. We developed four spectrally distinct fluorescent proteins, iRFP670, iRFP682, iRFP702, and iRFP720, from bacterial phytochromes. iRFPs exhibit high brightness in mammalian cells and tissues and are suitable for long-term stud...

Sumario: | Near-infrared fluorescent proteins are in high demand for in vivo imaging. We developed four spectrally distinct fluorescent proteins, iRFP670, iRFP682, iRFP702, and iRFP720, from bacterial phytochromes. iRFPs exhibit high brightness in mammalian cells and tissues and are suitable for long-term studies. iRFP670 and iRFP720 enable two-color imaging in living cells and mice using standard approaches. Five iRFPs including previously engineered iRFP713 allow multicolor imaging in living mice with spectral unmixing. |
