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
The Fundamentals and History of Fluorescence and Quantum Dots
At some point in your research and science career, you will no doubt come across fluorescence microscopy. This ubiquitous technique has transformed the way in which microscopists can image, tag and…Read article
Real Time Observation of Neutrophil White Blood Cell Recruitment to Bacterial Infection In Vivo
The zebrafish (Danio rerio) is an emerging vertebrate model organism to study infection. The transparent larva comprises a fully functional innate immune system and enables live imaging of fluorescent…Read article
What is Photomanipulation?
The term photomanipulation describes a wide range of techniques that enable the microscopist the transition from passive observer to instigator of events by offering a way of interacting with their…Read article
Photoactivatable, photoconvertible, and photoswitchable Fluorescent Proteins
Fluorescent proteins (FPs) such as GFP, YFP or DsRed are powerful tools to visualize cellular components in living cells. Nevertheless, there are circumstances when classical FPs reach their limits.…Read article
Clap On, Clap Off. Protein On, Protein Off
Unlike genetic or pharmacological manipulation, light-controlled proteins respond immediately, can be temporally and spatially triggered, are reversible, and are specific to the protein of interest.…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
Video Talk by Roger Tsien: Fluorescent Proteins
Live cell imaging has been revolutionized by the discovery of the green fluorescent protein (GFP). This lecture covers the history of GFP, how it folds and becomes fluorescent, how it has been mutated…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
Correlative In-Resin Super-Resolution and Electron Microscopy Using Standard Fluorescent Proteins
We introduce a method for correlative in-resin super-resolution fluorescence and electron microscopy (EM) of biological structures in mammalian culture cells. Cryo-fixed resin embedded samples offer…Read article
Nanoscale Protein Diffusion by STED-Based Pair Correlation Analysis
We describe for the first time the combination between cross-pair correlation function analysis (pair correlation analysis or pCF) and stimulated emission depletion (STED) to obtain diffusion maps at…Read article
Spectral and Structural Comparison Between Bright and Dim Green Fluorescent Proteins in Amphioxus
The cephalochordate Amphioxus naturally co-expresses fluorescent proteins (FPs) with different brightness, which thus offers the rare opportunity to identify FP molecular feature/s that are associated…Read article
Colonization of Potato Rhizosphere by GFP-Tagged Bacillus subtilis MB73/2, Pseudomonas sp. P482 and Ochrobactrum sp. A44 Shown on Large Sections of Roots Using Enrichment Sample Preparation and Confocal Laser Scanning Microscopy
The ability to colonize the host plants’ rhizospheres is a crucial feature to studyin the case of Plant Growth Promoting Rhizobacteria (PGPRs) with potential agricultural applications. In this work,…Read article
Imaging Pheromone Sensing in a Mouse Vomeronasal Acute Tissue Slice Preparation
In mice, the ability to detect pheromones is principally mediated by the vomeronasal organ (VNO). Here, an acute tissue slice preparation of VNO for performing calcium imaging is described. This…Read article
Sample Preparation for GSDIM Localization Microscopy – Protocols and Tips
The widefield super-resolution technique GSDIM (Ground State Depletion followed by individual molecule return) is a localization microscopy technique that is capable of resolving details as small as…Read article
