The following pages are in this category, out of total. This list may not reflect recent changes (learn more). In this video we show how to make fluorescein, a strongly fluorescent chemical. Combine 1mg of phthalic.

This guide will show you how to make fluorescent dye by disassembling a highlighter.

English dictionary definition of fluorescent dye. This is ideal for dying T-Shirts and coloring paper, however, some fabrics may not stain very well. Emission occurs only after absorbing light or electromagnetic radiation at a specific wavelength. Emission light is usually of longer wavelength than the absorbed light.

Fluorescent Dye Overview. One of the most well-known natural fluorescent probes is Green . A selection of fluorescent dyes that are a valuable tool for producing high quality images and studying biological systems.

Their spectra, however, can overlap with the 2nm wavelength used to quantitate nucleic acids. When attempting to measure the UV absorbance of a fluorescently labeled nucleic acid for the purpose of quantitation, therefore, the contribution from the fluorescent . A basic principle in fluorescence microscopy is the highly specific visualization of cellular components with the help of a fluorescing agent. This can be a fluorescing protein – for example GFP – genetically linked to the protein of interest. If cloning is impossible – for instance in histologic samples – it is . As such, they have now become the detection method of choice for tracing the presence of specific biomolecules in cells, cell . Sedgwick EG(1), Bragg PD.

Author information: (1) Department of Biochemistry, University of British Columbia, Vancouver, Canada. A cationic fluorescent dye which specifically binds to adenine-thymine-rich DNA. Applications include detection of nanogram quantities of DNA in cellular homogenates, and cytofluorometric determination of the DNA base content in human chromosomes.

Available in bulk quantities for OEM users at significant savings. Find the right fluorescent dye for staining of microscopic structures like cell tissues or other structures. In addition to dyes and fluorochromes we offer different filter sets for all kind of applications.

Dye tracing studies can also provide useful information for modeling surface and groundwater systems in addition to tracing contaminants. BMeS-p-A (1) is a novel synthetic dye.

Due to its unique and symmetrical molecular design, shows green fluorescence despite its small molecular size ( Table1). Stokes shifts up to 1nm due to a large conformation change in the excited-state. The absorption and fluorescence properties of are. XenoLight DiR lipophilic, NIR fluorescent cyanine dye ideal for staining cytoplasmic membrane.

Ideal for in vivo imaging of T-cell or stem cell homing. Atto labels represent a comprehensive series of fluorescent labels for biomolecules, which are designed for highest sensitivity applications. A unique combination of advantages makes them highly favorable tools for all kinds of labeling applications. In live cells the nonfluorescent calcein AM is converted to green- fluorescent calcein, after acetoxymethyl ester hydrolysis by intracellular esterases.
