Far-red fluorescent protein for whole body imaging
For deep imaging of animal tissues, the optical window favorable for light penetration is in near-infrared region, which requires fluorescent labels with far-red emission. Evrogen TurboFP635 (scientific name Katushka, see Shcherbo et al., 2007) is a far-red fluorescent protein with emission maximum at 635 nm. It is 7 to 10-fold brighter compared to the spectrally close HcRed or mPlum and characterized by fast maturation and high pH- and photostability. These unique characteristics make TurboFP635 the protein of choice for visualization within living tissues and dual-color high-throughput assays.
