Fluorescent Dye - an overview | ScienceDirect Topics
Fluorescent dyes, also known as reactive dyes or fluorophores, have been used by biologists for decades. Fluorescent dyes offer higher photostability and brightness compared to fluorescent proteins and do not require a maturation time.
Fluorescent Dyes Types, Vs Proteins, Applications Etc.
Fluorescent dyes (also known as fluorophores/reactive dyes) may simply be described as molecules (non-protein in nature) that, in microscopy, achieve their function by absorbing light at a given wavelength and re-emitting it at a longer wavelength.
Fluorescence Fundamentals | Thermo Fisher Scientific - US
Fluorescence is the result of a three-stage process that occurs in certain molecules (generally polyaromatic hydrocarbons or heterocycles) called fluorophores or fluorescent dyes (Figure 1). A fluorescent probe is a fluorophore designed to respond to a specific stimulus or to localize within a specific region of a biological specimen.

LAMP Fluorescent Dye - NEB
The LAMP Fluorescent Dye is an intercalating dye that can be used to track a LAMP reaction in real-time by fluorescence measurement. It is provided at 50X concentration and includes an amount sufficient for at least 500 LAMP reactions (0.5 µl per 25 µl LAMP reaction is recommended when monitoring reactions on most real time qPCR instruments).
The Light Spectrum and its Relationship with Fluorescence
A fluorescent dye absorbs light over a range of wavelengths—and every dye has a characteristic excitation range. However, some wavelengths within that range are more effective for excitation than other wavelengths. This range of wavelengths reflects the range of possible excited states that the fluorophore can achieve.
Fluorescence Definition and Examples - Science Notes and Projects
2023年4月5日 · Fluorescence is a phenomenon where certain materials rapidly (around 10 -8 seconds) emit light when they are exposed to specific types of electromagnetic radiation, typically ultraviolet (UV) light. Fluorescent materials are those that can exhibit this characteristic.
The category of molecules capable of undergoing electronic transitions that ultimately result in fluorescence are known as fluorescent probes, fluorochromes, or simply dyes. Fluorochromes that are conjugated to a larger macromolecule (such as a nucleic acid, lipid, enzyme, or protein) through adsorption or covalent bonds are termed fluorophores.
