Abstract
We report the engineering of mScarlet, a truly monomeric red fluorescent protein with record brightness, quantum yield (70%) and fluorescence lifetime (3.9 ns). We developed mScarlet starting with a consensus synthetic template and using improved spectroscopic screening techniques; mScarlet's crystal structure reveals a planar and rigidified chromophore. mScarlet outperforms existing red Förster proteins as a fusion tag, and it is especially useful as a fluorescence resonance energy transfer (FRET) acceptor in ratiometric imaging.
