Fig. 1 Correlative imaging. (A) Images of the same area are acquired in different modes.The confocal and STED images are acquired in reflection, while the AFM probe reaches the sample from above, providing a three-dimensional topographical view at high resolution.

8 Dec 2020 We correlate stimulated-emission-depletion microscopy of proteins and synchrotron X-ray fluorescence imaging of trace metals, both performed

In specimens eGFP can yield good results. A dedi-cated STED objective provides chromatic optimi- 2010-07-14 2021-03-26 A STED microscope has recently been completed in the Imaging Core facility. It is an all-pulsed, laser-scanning STED microscope that is unique in that it uses a Spatial Light Modulator to more controllably create the donut pattern required for depletion. The STED microscope: 640nm pulsed excitation. 775nm (~1ns) pulsed depletion. SLM 2020-12-08 2PLSM preclude the accurate imaging of many small subcellular features of neurons. Stimulated emission depletion (STED) microscopy is a superresolution imaging modality which overcomes the resolution limit imposed by diffraction and allows fluorescence imaging of nanoscale features.

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. Microscope start-up. 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. Light-Sheet Imaging.

9 Apr 2016 Resolution of STED microscopy is higher than confocal microscopy. All cells were infected with HSV-1 17+ strain for 6 h, then prepared for FISH

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 STED imaging of dendritic spines in living hippocampal slices. Hippocampal slices (300 μm thick) from YFP transgenic mice (Thy1-YFPH; prepared on postnatal days 5–7) lend themselves for studying spines with STED microscopy, as several distinct populations of neurons, including the CA1 pyramidal neurons, are strongly but sparsely labeled (Feng et al., 2000).

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.

The beam splitter in the system is replaced by a custom-made 2 mm thick dichroic mirror (ZT670dcrb, Chroma, USA).

The images were acquired before (leftmost image) and after the plasticity-inducing stimulation at the times indicated.

At a smaller scale, super-resolving fluorescence microscopy (right) for Live-Cell Labeling: Synthesis, Spectra and Super-Resolution STED,

The performance of STED microscopy is affected by many factors, of which aberrations induced by the optical system and biological samples can distort the wave front of the depletion beam at the focal plane to 2PLSM preclude the accurate imaging of many small subcellular features of neurons. Stimulated emission depletion (STED) microscopy is a superresolution imaging modality which overcomes the resolution limit imposed by diffraction and allows fluorescence imaging of nanoscale features. In this thesis, I describe the development of 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 STED imaging of dendritic spines in living hippocampal slices.
