Step 2: Choice of fluorophores There is a wide range of fluorophores performing well with STED imaging and experiments with low labeling densities designed to stay close to physiological conditions are typical. At the same time, the dead-time compensation of DynamicPLUS allows crisp images of high-signal samples, such as bright confocal images. STEDYFOCUS Module. 2020-04-07 As the spatial resolution of STED imaging correlates with an increase in STED light intensity, photodegradation of fluorescent dyes becomes a serious issue. Representative photoresistant fluorescent dyes such as Alexa Fluor® 488 and ATTO 488 are also known to encounter photodegradation in STED microscopy, making it difficult to conduct continuous live-imaging of biological systems while Super-resolution imaging using the principles of stimulated emission depletion (STED) microscopy requires collinear excitation of a sample with a Gaussian-shaped excitation beam and a donut-shaped depletion beam whose spin (polarization) and orbital angular momentum (OAM) signs are aligned.

Fig. 4 illustrates the types of structural changes that can be observed by STED imaging. The images were acquired before (leftmost image) and after the plasticity-inducing stimulation at the times indicated. This ultimately enables imaging of triple color labeling with the 592 STED line (e.g. ST AR 440SX, Oregon Green 488 and Alexa Fluor 532).

Cellular Imaging Techniques for Neuroscience and Beyond

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. 2020-05-19 · STED imaging with this mask (2D STED) increases the lateral resolution (Fig. 1 B) but leaves axial resolution unchanged (Fig. 1 D). In our microscope, the phase mask was created by an SLM, and as such, it could be swapped to any other phase mask to change the STED confinement mode without changing the optical layout. 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. 2021-03-15 · Cell imaging.

Superupplösningsmikroskopi - Super-resolution microscopy

2020-05-19 STED instruments utilize a raster-scan imaging scenario similar to a laser-scanning confocal microscope. In contrast, stochastic optical reconstruction microscopy ( STORM ), as performed using Nikon's N-STORM system, is a single-molecule approach that relies on activation of a limited subset of the overall molecular population to sequentially image and localize individual emitters on a 2020-03-01 2017-02-28 2008-12-02 2019-09-30 Using a commercial STED microscope and restricting imaging to smaller field of views allowed STED imaging at a frame rate of 0.4 to 0.8 Hz (Supplementary Videos 5 and 6). Because Nile Red can be effectively depleted using far-red depletion lasers (here λ dep = 775 nm), it can be combined with other membrane permeable labels, for example, live-cell compatible SiR-conjugates. 2018-06-22 STED Imaging Works With Quantum Dots Quantum dots survive more than 1,000 scan cycles, could be useful for time-lapse imaging by Celia Henry Arnaud June 1, 2015 | APPEARED IN VOLUME 93, ISSUE 22 We report Stimulated Emission Depletion (STED) imaging of green fluorescent nanodiamonds containing Nitrogen-Vacancy-Nitrogen (NVN) centers with a resolution of 70 nm using a commercial microscope.
