TauSense Technology Imaging Tools

Leica Microsystems’ TauSense technology is a set of imaging modes based on fluorescence lifetime. Found at the core of the STELLARIS confocal platform, it will revolutionize your imaging experiments.…

Super-resolved STED spectroscopy

Molecular interactions are key in cellular signalling. They are often ruled or rendered by the mobility of the involved molecules.

Step by Step Guide for FRAP Experiments

Fluorescence Recovery After Photobleaching (FRAP) has been considered the most widely applied method for observing translational diffusion processes of macromolecules. The resulting information can be…

Widefield Calcium Imaging with Calcium Indicator Fura2

In eukaryotic cells Ca2+ is one of the most widespread second messengers used in signal transduction pathways. Intracellular levels of Ca2+ are usually kept low, as Ca2+ often forms insoluble…

Fluorescence Correlation Spectroscopy (FCS)

Fluorescence correlation spectroscopy (FCS) measures fluctuations of fluorescence intensity in a sub-femtolitre volume to detect such parameters as the diffusion time, number of molecules or dark…

Fluorescence Recovery after Photobleaching (FRAP) and its Offspring

FRAP (Fluorescence recovery after photobleaching) can be used to study cellular protein dynamics: For visualization the protein of interest is fused to a fluorescent protein or a fluorescent dye. A…

Förster Resonance Energy Transfer (FRET)

The Förster Resonance Energy Transfer (FRET) phenomenon offers techniques that allow studies of interactions in dimensions below the optical resolution limit. FRET describes the transfer of the energy…
