We describe a STED microscope optimized for colocalization experiments with up to three colors. Two fluorescence labels are separated by their fluorescence lifetime whereas a third channel is discriminated by the wavelength of fluorescence emission. Since it does not require...

Fluorescent markers emitting in the red are extremely valuable in biological microscopy since they minimize cellular autofluorescence and increase flexibility in multicolor experiments. Novel rhodamine dyes excitable with 630 nm laser light and emitting at around 660 nm have been...
Stimulated emission depletion (STED) microscopy usually employs a scanning excitation beam that is superimposed by a donut-shaped STED beam for keeping the fluorophores at the periphery of the excitation spot dark. Here, we introduce a simple birefringent device that produces...

This study presents the use of flow cytometry as a high-throughput quantifiable technique to study multicomponent adsorption interactions between proteins and surfaces. Flow cytometry offers the advantage of high-throughput analysis of multiple parameters on a very small sampling scale. This...
Reorganization of Lipid Diffusion by Myelin Basic Protein as Revealed by STED Nanoscopy.
We report on a straightforward yet powerful implementation of stimulated emission depletion (STED) fluorescence microscopy providing subdiffraction resolution in the far-field. Utilizing the same super-continuum pulsed laser source both for excitation and STED, this implementation of STED microscopy avoids elaborate...

Fluorescence resonance energy transfer (FRET) using biotinylated β-galactosidase (βGAL) as a donor and Alexa Fluor 350 (AF350) labeled avidin as an acceptor has been investigated by means of steady-state fluorescence and time-resolved fluorescence spectroscopy. The donors are readily paired with...

Self-Calibrated Line-Scan STED-FCS to Quantify Lipid Dynamics in Model and Cell Membranes.
We report stimulated emission depletion (STED) fluorescence microscopy with continuous wave (CW) laser beams. Lateral fluorescence confinement from the scanning focal spot delivered a resolution of 29-60 nm in the focal plane, corresponding to a 5-8-fold improvement over the diffraction...

Post-fusion structural changes and their roles in exocytosis and endocytosis of dense-core vesicles.
Herein we report a method for the detection of methylated CpG dinucleotides located within CpG islands in genomic DNA using multiplexed bead-based assays and standard flow cytometry instrumentation. Four CpG "clusters" were identified in the TFPI2 and SPARC CpG islands...
