Photoactivatable fluorophores
WebPhotoactivatable fluorophores afford powerful mol. tools to improve the spatial and temporal resoln. of subcellular structures and dynamics. By performing a single sulfur-for-oxygen atom replacement within common fluorophores, the authors have developed a facile and general strategy to obtain photoactivatable fluorogenic dyes across a broad ... WebAdditionally, targeting ligands can be incorporated in the resulting photoactivatable fluorophores (PAFs) to label selected subcellular components in live cells. Indeed, photoactivatable BODIPYs have already allowed the sub-diffraction imaging of diverse cellular substructures in live cells using PALM and can evolve into invaluable analytical ...
