Generation of monomeric reversibly switchable red fluorescent proteins for far-field fluorescence nanoscopy.
Reversibly switchable fluorescent proteins (RSFPs) are GFP-like proteins that may be repeatedly switched by irradiation with light from a fluorescent to a nonfluorescent state, and vice versa. They can be utilized as genetically encodable probes and bear large potential for a wide array of applications, in particular for new protein tracking schemes and subdiffraction resolution microscopy. How...
متن کاملTeal fluorescent proteins: Characterization of a reversibly photoswitchable variant
Fluorescent proteins (FPs) emerged in the mid 1990s as a powerful tool for life science research. Cyan FPs (CFPs), widely used in multicolor imaging or as a fluorescence resonance energy transfer (FRET) donor to yellow FPs (YFPs), were considerably less optimal than other FPs because of some relatively poor photophysical properties. We recently initiated an effort to create improved or alternat...
متن کاملReversibly switchable DNA nanocompartment on surfaces.
Biological macromolecules have been used to fabricate many nanostructures, biodevices and biomimetics because of their physical and chemical properties. But dynamic nanostructure and biomachinery that depend on collective behavior of biomolecules have not been demonstrated. Here, we report the design of DNA nanocompartments on surfaces that exhibit reversible changes in molecular mechanical pro...
متن کاملReversibly switchable fluorescence microscopy with enhanced resolution and image contrast.
Confocal microscopy with optical sectioning has revolutionized biological studies by providing sharper images than conventional optical microscopy. Here, we introduce a fluorescence imaging method with enhanced resolution and imaging contrast, which can be implemented using a commercial confocal microscope setup. This approach, called the reversibly switchable photo-imprint microscopy (rsPIM), ...
متن کامل1.8 A bright-state structure of the reversibly switchable fluorescent protein Dronpa guides the generation of fast switching variants.
RSFPs (reversibly switchable fluorescent proteins) may be repeatedly converted between a fluorescent and a non-fluorescent state by irradiation and have attracted widespread interest for many new applications. The RSFP Dronpa may be switched with blue light from a fluorescent state into a non-fluorescent state, and back again with UV light. To obtain insight into the underlying molecular mechan...
