Shorter Wavelength Expands Fluorophore’s Role in Monitoring Cell Dynamics . OSAKA, Japan, Nov. 28, 2022 — A genetically modified fluorescent protein has exhibited the shortest fluorescence emission wavelength to date, researchers at Osaka University reported. The fluorophore, named Sumire, emits 414-nm violet fluorescence from a hydrated chromophore. The development of Sumire will make it possible for scientists to track a larger number of biomolecules at the same time, ...
