The absorption values were collected using a spectral bandwidth of 1.0 nm, a signal averaging time of 0.133 sec, a data interval of 0.25 nm, and a scan rate of 112.5 nm/min. UV light shows higher phototoxicity than red light38,39 and should be used only at low intensities and/or low pulse frequencies. This buffer was supplemented with 50mM KCl, 2mM MgCl2, 5mM guanidine carbonate and 1mM ATP to obtain F-actin. Use the extinction coefficient () of rhodamine B ( 555 = M. Chem.

The dark counts were subtracted and the spectra were corrected for wavelength-dependent instrument sensitivity. and K.J. This apparent fluorogenicity of the probe should prove beneficial for live-cell imaging as unconjugated PA-SiR-Halo is not fluorescent, which increases the signal-to-background ratio. 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. Nat Commun 10, 4580 (2019). Data were corrected for air and detector absorption, Lorentz and polarization effects43 and scaled essentially by application of appropriate spherical harmonic functions43,45,46. The extinction coefficients used for TRITC/ConA conjugates under native and denaturing conditions were 6.52 x 104 M-~ cm-~ and 6.96 x 104 M-1 cm-1, respectively.

It has to be noted that the use of (high-intensity) UV light for photoactivation can cause fluorophore degradation and phototoxicity. Article It should be noted that other PA-SiR probes can be generated (Supplementary Figs. Phys. 15). Bioinformatics 30, 23892390 (2014).

Nuclear pores possess a regular circular shape with an internal diameter of about 100nm33,34. An illumination correction was performed as part of the numerical absorption correction45. Farrugia, L. WinGX and ORTEP for Windows: an update. Rhodamines have also been rendered photoactivatable through a diazoketone group19, leading to the introduction of the photoactivatable Janelia Fluor dyes PA-JF549 and PA-JF64620, which have been successfully used for fixed-cell and live-cell SMLM. fh Confocal images of several HaloTag fusion proteins stained with PA-SiR-Halo (0.5M for 1.5h): f microtubules (CEP41-Halo). Other properties listed for this fluorescent dye include the physical form, solubility, absorption maxima, emission maxima, molar extinction coefficient and quantum yield. The absorption of R6G in different solvents . UV irradiation was performed directly inside the spectrophotometer during the ongoing experiment for 12s unless otherwise stated. Representative measurements are displayed. Fitted parameters such as decay constants etc. These values were obtained from a model dye complex formed between TRITC and E-amino-n-caproic acid which . Fluorescence was collected through a high-numerical aperture (NA) oil-immersion objective (160/1.43 NA; Leica), filtered by a 700/100 bandpass filter (AHF) and focused onto an Evolve512D EMCCD camera (Photometrics). Quantum yields of activation were determined using standard ferroxialate actinometry41 along with the activation rates determined in the saturation experiments (Supplementary Fig. Sect. coefficient ( ) is used in place of extinction coefficient; absorbance (A) in lieu of optical density (OD).

Use the Previous and Next buttons to navigate the slides or the slide controller buttons at the end to navigate through each slide. Most interestingly, localizing the fluorophore to the outer membrane of the mitochondria further enabled us to distinguish the outer membrane from the matrix in several cases (red arrowheads), which has not been observed with live-cell SMLM so far.
