Fluorescent Dye
Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.
Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.
Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

Coumarin 343 azide
0 ImagesCat. No.: HY-D3521CAS No.: 1807503-82-7Coumarin 343 azide is a fluorescent dye used for the fluorescent labeling of alkyne-containing biomolecules based on click chemistry. Its detection mechanism relies on the copper (I)-catalyzed azide-alkyne cycloaddition (CuAAC), a type of click reaction: under mild aqueous conditions, the azide group of this dye selectively reacts with the alkyne moiety of propargyl geldanamycin to form a triazole bond that conjugates the fluorescent dye to the target biomolecule; fluorescence is generated upon successful conjugation to the target.
