Photoactivatable fluorophores
WebOct 27, 2024 · The photoactivatable derivates are formed from any suitable fluorophore, such as, but not limited to, fluorophores containing one or more cyclic amine substituents. For example, in one embodiment, the photoactive fluorophores include photoactivatable derivatives of an azetidine-containing “Janelia-Fluor” (JF) dye. WebFeb 27, 2024 · Photoactivatable fluorophores switch from a nonemissive to an emissive state upon illumination at an activating wavelength and then emit after irradiation at an exciting wavelength.

WebOct 23, 2024 · The use of photoactivatable dyes in STED microscopy has so far been limited by two-photon activation through the STED beam and by the fact that photoactivatable dyes are poorly solvable in water. Herein, we report ONB-2SiR, a fluorophore that can be both photoactivated in the UV and specifically de-excited by STED at 775 nm. WebSmall-molecule fluorophores are important tools for advanced imaging experiments. We previously reported a general method to improve small, cell-permeable fluorophores which resulted in the azetidine-containing 'Janelia Fluor' (JF) dyes. Here, we refine and extend the utility of these dyes by synthesizing photoactivatable derivatives that are ...
WebFluorophores emit a limited number of photons before bleaching, so it's important to collect as many as possible. While we can sometimes compensate for poor excitation efficiency simply by increasing the illumination light power (at the potential cost of phototoxicity), the same cannot be said for poor collection efficiency: those lost emission ...
