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
Phasor Analysis for FLIM (Fluorescence Lifetime Imaging Microscopy)
The Phasor analysis approach to analyze fluorescence lifetime does not require any fitting. Phasor FLIM (fluorescence lifetime imaging microscopy) provides a 2D graphical view of lifetime…Read article
FLIM FRET and Biosensors: Versatile Tools for Biomedical Research
Fluorescence Lifetime Imaging (FLIM) in combination with Förster Resonance Energy Transfer (FRET) has proven to be very beneficial for investigations in biomedical research for a wide range of…Read article
FLIM FRET - Förster Resonance Energy Transfer
A typical application of FLIM is FLIM-FRET. FRET is a well-established technique to study molecular interactions. It scrutinizes protein binding and estimates intermolecular distances on an Angström…Read article
Lifetime – a Proper Alternative
„Way too complicated!“ - the notorious feedback when it comes to fluorescence lifetime measurements. This will change now! New technologies and new concepts for data evaluation, all implemented in…Read article
Video Talk by Roger Tsien: Fluorescent Protein Indicators
In this talk, Roger Tsien discusses how fluorescent proteins have been turned into indicators for a wide variety of biological molecules, including pH, ions, redox potential, and signaling molecules…Read article
Fluorescent Proteins Illuminate Cell Biology
Green fluorescent protein (GFP) isolated from the jellyfish Aequorea victoria and GFP-like fluorescent proteins from other animals have had an important role in the technical innovations that have…Read article
Universal PAINT – Dynamic Super-Resolution Microscopy
Super-resolution microscopy techniques have revolutionized biology for the last ten years. With their help cellular components can now be visualized at the size of a protein. Nevertheless, imaging…Read article
ICln: A New Regulator of Non-Erythroid 4.1R Localisation and Function
To optimise the efficiency of cell machinery, cells can use the same protein (often called a hub protein) to participate in different cell functions by simply changing its target molecules. There are…Read article
Novel Fluorescent Carbonic Nanomaterials for Sensing and Imaging
Small brightly fluorescent carbon nanoparticles have emerged as a new class of materials important for sensing and imaging applications. We analyze comparatively the properties of nanodiamonds,…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
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
Live-cell Imaging Techniques
The understanding of complex and/or fast cellular dynamics is an important step for exploring biological processes. Therefore, today’s life science research is increasingly focusing on dynamic…Read article
Modern Fluorescent Proteins and their Biological Applications
Here we present two review articles on fluorescent proteins and their biological applications. These first article reviews our current knowledge of blue, green, and red chromophore formation in…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
