Here, we demonstrate confocal and STED microscopy with short, fluorophore-labeled oligonucleotides that transiently bind to complementary oligonucleotides attached to protein-specific antibodies. The constant exchange of fluorophore labels in DNA-based STED imaging bypasses photobleaching that occurs with covalent labels.

To enhance contrast, raw 2P-STED image stacks were subjected to deconvolution (Huygens HuCore version 17.4, Scientific Volume Imaging b.v., Hilversum, The Netherlands) utilizing a theoretical PSF based on microscope parameters and classic maximum likelihood estimation (cmle) with a quality stop criterion of 0.01, automatic background estimation and a signal-to-noise ratio (SNR) of 15.

Optimization of the STED parameters taking into account the sample itself is therefore a complex task as there is no clear methodology that can determine the image improvement in an 2012-08-15 · Imaging and physiology data were acquired using data acquisition boards (National Instruments, Austin, TX) and modiﬁed versions of the software ScanImage (14) with code written in MATLAB (The MathWorks, Natick, MA). STED laser powers were measured at the output of the microscope objective. Live neuron imaging was performed with a time-averaged Christian Eggeling Group in Jena Biophysical Imaging Lab - Super-resolution microscopy and membrane biophysics. STED, MINFLUX, FCS, iSCAT, SIM, SMLM, STED-FCS. Professor Prof. Christian Eggeling. Friedrich-Schiller University Jena and Leibniz Institute of 9 Jul 2020 Stimulated emission depletion (STED) microscopy provides super-resolved images by selective deactivation of fluorophores in the outer region First, we compare the STED performance imaging single molecules of several common dyes and report a novel STED dye. Then we apply STED to image 19 May 2020 Stimulated emission depletion (STED) microscopy does not suffer from these shortcomings despite having a lower axial resolution (20).

STED microscopy is typically 11 Oct 2019 Here, we demonstrate confocal and STED microscopy with short, fluorophore‐ labeled oligonucleotides that transiently bind to complementary STED microscopy breaks Abbe's diffraction barrier. · TDE embedding preserves STED resolution along the axial plane in thick samples. · Improving resolution in the Stimulated Emission Depletion (STED) microscopy has been convincingly demonstrated for fundamental studies in cells, living tissue and organisms. Today 19 May 2020 Stimulated emission depletion (STED) microscopy is a versatile imaging method with diffraction-unlimited resolution. Here, we present a novel 8 Dec 2020 We correlate stimulated-emission-depletion microscopy of proteins and synchrotron X-ray fluorescence imaging of trace metals, both performed 8 Aug 2019 The physical idea of STED microscopy is very simple. With the Multicolour STED imaging with a single STED laser is also possible; and the Download scientific diagram | Super-resolution stimulated emission depletion ( STED) imaging in optically cleared kidney samples.

Our STED technology joins the STELLARIS platform to provide you the fastest way of imaging beyond the diffraction limit. Obtain cutting-edge nanoscopy results in no time with astounding image quality and resolution, while protecting your sample. Introductory guide to STED super-resolution imaging using the Leica Microsystems TCS SP8 STED 3X.

14 Aug 2019 For STED microscopy right now, the standard of resolution is between 20 and 40 nm depending on the fluorophore, and depending on the

Alexa 488, Alexa Fluor 532 and TMR). STED microscopy delivers the most reliable super-resolved Then, the cells were washed 3 time with fresh medium to remove the free dye, and kept in DMEM+ for imaging. The Leica TCS SP8 STED 3× system with 2 CW lasers at 592 and 660 nm and a pulsed laser at 775 nm for the depletion was used for STED imaging.

Imaging dendritic spines in the hippocampus in vivo is challenging because of its remote location more than 1 mm below the surface of the mouse brain. A pioneering study accomplished this with two-photon (2P) microscopy, but only over a period of a few hours (Mizrahi et al., 2004).

Switch on the PC Microscope, Scanner Power and Laser Power buttons and turn the Laser Emission key from Off to On. Wait for the computer to boot up, login to the account and then turn on the depletion lasers.

Remarkably, stimulated emission depletion imaging with AIE dots is achieved for the first time, and the spatial resolution is significantly enhanced to ≈95 nm. For single color STED imaging, SiR-tubulin or SiR-actin were added to DIV15 neurons in the BrainPhys medium at a final concentration of 1 µM during 1.5 hr at 37°C. For dual color imaging, SiR-tubulin and SiR700-actin were added to to the BrainPhys medium at 1 µM final concentration each and neurons were exposed during 1.5 hr at 37°C. Due to relatively high powers used in STED, biological samples may be affected by the illumination in the process of image acquisition. Similarly, the performance of the system may be limited by the sample itself.

19 Jun 2012 In contrast to any currently used super resolution techniques, STED microscopy possesses a unique set of advantages, such as, rapid image

50 nm resolution at 1-2 Hz. 100 x 100 mm field of view. Time lapse imaging; STED-FCS 2020-11-11 · STED imaging. Confocal and STED images were obtained at a Leica TCS SP8‐3X gated STED system (Leica Microsystems) equipped with a pulsed white light laser (WLL, tunable from 470 to 670 nm) for 2020-03-01 · Importantly, nanoscale imaging requires high local stability of the imaging area in relation to the STED microscope. Any movement of the imaging area within the acquisition time caused by vibrations of the microscope, vital functions of the mouse such as heart beat, or pressure pulse, or thermal drift leads to distorted images.
