38 fluorescent labels and light microscopy

Fluorescence Microscopy - Explanation and Labelled Images Fluorescence microscopy uses a high-intensity light source that excites a fluorescent molecule called a fluorophore in the sample observed. The samples are labeled with fluorophore where they absorb the high-intensity light from the source and emit a lower energy light of longer wavelength.

Fluorescent tag - Wikipedia Fluorescent tag. S. cerevisiae septins revealed with fluorescent microscopy utilizing fluorescent labeling. In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid. Label-free prediction of three-dimensional fluorescence images from ... Fluorescence microscopy can resolve subcellular structure in living cells, but is expensive, slow, and toxic. Here, we present a label-free method for predicting 3D fluorescence directly from transmitted light images and demonstrate its use to generate multi-structure, integrated images. Label-free prediction of three-dimensional fluorescence images from ... Label-free prediction of three-dimensional fluorescence images from transmitted-light microscopy Understanding cells as integrated systems is central to modern biology. Although fluorescence microscopy can resolve subcellular structure in living cells, it is expensive, is slow, and can damage cells.
