Abstract
To perform correlation analysis between different physiological parameters using fluorescent protein-based functional probes, diversification of wavelength properties of fluorescent proteins is underway. However, the shortest emission wavelength of fluorescent proteins has not been updated for more than 10 years. Here, we report the development of Sumire, a fluorescent protein emitting 414 nm violet fluorescence from a hydrated chromophore. The Sumire’s fluorescence property allows for the creation of FRET probes that can be used simultaneously with CFP-YFP based FRET probes for multi-parameter analysis.
A violet fluorescent protein with emission wavelength 414 nm is engineered.
