Journal ArticleDOI
Fluorogenic probes for live-cell imaging of the cytoskeleton.
Gražvydas Lukinavičius,Luc Reymond,Elisa D’Este,Anastasiya Masharina,Fabian Göttfert,Haisen Ta,Angelika Güther,Mathias Fournier,Stefano Rizzo,Herbert Waldmann,Claudia Blaukopf,Christoph Sommer,Daniel W. Gerlich,Hans-Dieter Arndt,Stefan W. Hell,Kai Johnsson +15 more
TL;DR: Far-red, fluorogenic probes are introduced that reveal the ninefold symmetry of the centrosome and the spatial organization of actin in the axon of cultured rat neurons with a resolution unprecedented for imaging cytoskeletal structures in living cells.
Journal ArticleDOI
Sharper low-power STED nanoscopy by time gating
Giuseppe Vicidomini,Gael Moneron,Kyu Young Han,Kyu Young Han,Volker Westphal,Haisen Ta,Matthias Reuss,Johann Engelhardt,Christian Eggeling,Stefan W. Hell +9 more
TL;DR: Applying pulsed excitation together with time-gated detection improves the fluorescence on-off contrast in continuous-wave stimulated emission depletion (CW-STED) microscopy, thus revealing finer details in fixed and living cells using moderate light intensities.
Journal ArticleDOI
Scanning STED-FCS reveals spatiotemporal heterogeneity of lipid interaction in the plasma membrane of living cells
Alf Honigmann,Veronika Mueller,Haisen Ta,Andreas Schoenle,Erdinc Sezgin,Stefan W. Hell,Christian Eggeling +6 more
TL;DR: The results do not support the presence of nanodomains based on lipid-phase separation in the basal membrane of the authors' cultured nonstimulated cells, and show that alternative interactions are responsible for the strong local trapping of their sphingolipid analogue.
Journal ArticleDOI
Fluorogenic Probes for Multicolor Imaging in Living Cells.
Gražvydas Lukinavičius,Luc Reymond,Keitaro Umezawa,Olivier Sallin,Elisa D’Este,Fabian Göttfert,Haisen Ta,Stefan W. Hell,Yasuteru Urano,Kai Johnsson +9 more
TL;DR: In conjunction with probes based on the previously introduced carboxy-SiR650, SiR700-based probes permit multicolor live-cell superresolution microscopy in the far-red, thus significantly expanding the capacity for imaging living cells.
Journal ArticleDOI
STED nanoscopy with time-gated detection: theoretical and experimental aspects.
Giuseppe Vicidomini,Andreas Schönle,Haisen Ta,Kyu Young Han,Gael Moneron,Christian Eggeling,Stefan W. Hell +6 more
TL;DR: A theoretical framework and experimental data are presented that characterize the time evolution of the effective point-spread-function of a STED microscope and illustrate the physical basis, the benefits, and the limitations of time-gated detection both for CW and pulsed STED lasers.
