Biol. Use the absorbance (A) of the solution at = 555 nm. Chem. Carbopyronine and fluorescein derivatives with such an exocyclic double bond have been described (see Supplementary Fig. In contrast to other photoactivatable fluorophores, no caging groups are required, nor are there any undesired side-products released. Photobiol. Genome-edited U-2 OS cells with Halo-tagged NUP9632 were seeded on 24mm round coverslips (No. Wldchen, S., Lehmann, J., Klein, T., van de Linde, S. & Sauer, M. Light-induced cell damage in live-cell super-resolution microscopy. Lateral drift was minimized by the suppressed motion (SuMo) stage of the Leica SR GSD and by keeping the temperature of the environment stable via an incubation box (T=210.1C, instrument parameter) covering the entire microscope. The highly dynamic mitochondria form thin tubules between neighboring mitochondria (blue arrowheads) and disconnect (fission) in other areas (yellow arrowheads). Chem. Spectra were measured with NS=128 using a water suppression presaturation sequence. The equilibrium between 2 and 3, as measured by recording the absorbance at equilibrium and correcting for Amax at 646nm (Aeq), was shifted toward 3 at higher pH values (Fig. are inventors on a patent filed by EPFL and Spirochrome AG. d, e Maximum projection of a z-stack of U-2 OS cells stably expressing H2B-Halo (nucleus) stained with PA-SiR-Halo (0.5m for 2h) before d and after UV irradiation e Scale bar, 40m.

We next tested the performance of PA-SiR-Halo in live-cell single-particle tracking photoactivated localization microscopy (sptPALM) (Fig. All nonhydrogen atoms were given anisotropic displacement parameters. 13b)20. Furthermore, the equilibrium of the reaction of activated PA-SiR with nucleophiles is environmentally sensitive. One of these SRM approaches is single-molecule localization microscopy (SMLM), which relies on the switching of fluorophores between an off and an on state3,4,5. The microscope was equipped with a CO2 and temperature controllable incubator (PeCon, 37C). HaloTag: a novel protein labeling technology for cell imaging and protein analysis. However, PA-SiR underwent protonation upon ultraviolet (UV) irradiation in aqueous solution, re-establishing the fluorescent xanthene core of SiR 2 (Fig. Trends Cell Biol. Nat. 18, 335-346. Scale bar, 100nm. CAS J. Luminesc. PubMed Rhodamine B / r o d m i n / is a chemical compound and a dye.It is often used as a tracer dye within water to determine the rate and direction of flow and transport. However, small-molecule fluorophores are generally brighter and more photostable than fluorescent proteins9, and therefore of advantage for SMLM experiments10,11. The solutions were incubated for 5min at room temperature, then mixed and incubated for additional 20min at room temperature. A solution of 2% [v/v] N-[3-(trimethoxysilyl)propyl]ethylendiamine (Sigma-Aldrich) in dry acetone was prepared and the clean coverslips were immersed in the dark for 1h.
