Advanced Quantitative Fluorescence Microscopy to Probe the Molecular Dynamics of Viral Entry
Viral entry into the host cell requires the coordination of many cellular and viral proteins in a precise order. Modern microscopy techniques are now allowing researchers to investigate these…Read article
FRAP with TCS SP8 Resonant Scanner
Fast FRAP experiments need a sufficient number of measurement points for meaningful interpretation and fitting analysis. To study very fast translocational processes, the use of a resonant scanner…Read article
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…Read article
Label-free FLIM
Many biological samples exhibit autofluorescence. Its often broad spectra can interfere with fluorescent labeling strategies. This application letter demonstrates how autofluorescence can serve as an…Read article
FRET with FLIM
FLIM combines lifetime measurements with imaging: lifetimes obtained for each image pixel are color-coded to produce additional image contrast. Thus, FLIM delivers information about the spatial…Read article
Fluorescence Correlation Spectroscopy
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…Read article
Quantitative Fluorescence
Seeing is believing – and measuring is knowing. Microscopes generate images that are not only used for illustration, but are also subject to quantification. More advanced techniques use illumination…Read article
FLCS – Advances in Fluorescence Correlation Spectroscopy
The characterization of substances at the single molecule level has become part of the standard repertoire of scientific research institutes. One of the most common methods is Fluorescence Correlation…Read article
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…Read article
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…Read article
