2015

2015/12/23. "Brighter Red Fluorescent Proteins by Rational Design of Triple-Decker Motif" is published online on the ACS Chemical Biology website. In this study, we used rational design to increase the quantum yield and brightness of red fluorescent proteins by rigidifying the chromophore via the creation of a triple-decker motif of aromatic rings (see figure on left).

2015/12/23. We recently used rational design to increase the quantum yield and brightness of red fluorescent proteins (RFPs) by rigidifying their chromophore via the creation of a triple-decker motif of aromatic rings (see figure below). The best mutant identified displayed an over three-fold improvement relative to the parent RFP and was isolated following the screening of only 48 mutants, a library size that is several orders of magnitude smaller than those previously used to achieve equivalent gains in quantum yield in other RFPs. This study was published in ACS Chemical Biology, and can be found here.
