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 -
The Oncogenic Triangle of HMGA2, LIN28B and IGF2BP1 Antagonizes Tumor-Suppressive Actions of the let-7 Family
The tumor-suppressive let-7 microRNA family targets various oncogene-encoding mRNAs. We identify the let-7 targets HMGA2, LIN28B and IGF2BP1 to form a let-7 antagonizing self-promoting oncogenic…Read article -
Time Gating of Chloroplast Autofluorescence Allows Clearer Fluorescence Imaging In Planta
Chloroplast, an organelle facilitating photosynthesis, exhibits strong autofluorescence, which is an undesired background signal that restricts imaging experiments with exogenous fluorophore in…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 -
A Brief History of Light Microscopy – From the Medieval Reading Stone to Super-Resolution
The history of microscopy begins in the Middle Ages. As far back as the 11th century, plano-convex lenses made of polished beryl were used in the Arab world as reading stones to magnify manuscripts.…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 -
Fluorescent Proteins – Introduction and Photo Spectral Characteristics
The prospects of fluorescence microscopy changed dramatically with the discovery of fluorescent proteins in the 1950s. The starting point was the detection of the jellyfish Aequorea victoria green…Read article -
Fluorescent Proteins - From the Beginnings to the Nobel Prize
Fluorescent proteins are the fundament of recent fluorescence microscopy and its modern applications. Their discovery and consequent development was one of the most exciting innovations for life…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 -
Nanoscopy in a Living Multicellular Organism Expressing GFP
We report superresolution fluorescence microscopy in an intact living organism, namely Caenorhabditis elegans nematodes expressing green fluorescent protein (GFP)-fusion proteins. We also…Read article -
Obese and Slim Yeast Cells
Lipids are on everyone’s lips nowadays, whether ω-3/6 fatty acids, good and bad cholesterol or just plain fat that has the annoying habit of accumulating on our hips. Serious diseases such as obesity,…Read article -
CLEM: Combining the Strengths of Light and Electron Microscopy
In recent years light microscopy studies have been dominated by live cell imaging while electron microscopy has been used for high-resolution studies. Latterly, there has been increasing interest in…Read article -
4D Photoactivation of pa-GFP in Living Cells Using Two-Photon Excitation Laser Scanning Microscopy
We report about two-photon activation of a photoactivatable derivative of the Aequorea Victoria green fluorescent protein (pa-GFP). This special form of the molecule increases its fluorescence…Read article
