Quantum yields of activation were determined using standard ferroxialate actinometry41 along with the activation rates determined in the saturation experiments (Supplementary Fig. & Medalia, O. Nature Communications (Nat Commun) This demonstrates that PA-SiR-Halo enables live-cell SMLM of intracellular targets. 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. Rhodamine Green and Rhodamine Green-X Dyes Carboxyrhodamine 110, which we have named Rhodamine Green dye, is the nonsulfonated analog of Alexa Fluor 488 dye. Chem. Nat. Van Walree Cornelis, A. et al. In addition, photoactivation of fluorophores caged with the diazoketone group proceeds through a carbene, which can react with intracellular nucleophiles (Supplementary Fig. The samples were incubated for 23h at 37C.

We found that PA-SiR-Halo showed an excellent signal-to-background ratio after activation under no wash conditions (325, mean95% confidence interval, N=119 cells) and that the fluorescence signal after activation was stable over time. However, in the absence of structural information on HaloTag labeled with PA-SiR-Halo we cannot provide more detailed insights on the nature of these interactions. Proteins were used from glycerol stocks and were further diluted. Cells were split every 34 days or at confluency. Grimm, J.

The next day the cells were stained with PA-SiR-Halo as described above and the coverslips were mounted into attofluor cell chambers (Life technologies) and the imaging medium was supplemented with HEPES (20mM). Phototoxicity caused by activation of small-molecule synthetic probes with UV light can be due to the UV light itself as well as toxic side products of the photoactivation.

However, with the many strategies available to tune the HOMOs and LUMOs of xanthene derivatives, we believe it should be feasible to generate photoactivatable rhodamine and carbopyronine derivatives, thereby expanding the scope of this reaction. However, this is less relevant for single-molecule based super-resolution microscopy since the observation period of individual fluorophores in SMLM is on the order of milliseconds and the reaction of activated PA-SiR with nucleophiles should not interfere in such experiments.
