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.

BP Fluor 405 alkyne triTEA
0 ImagesCat. No.: HY-W800694CAS No.: 2006335-63-1BP Fluor 405 alkyne triTEA is a blue-fluorescent dye that often used in multi-color applications, including flow cytometry and super-resolution microscopy using STORM. Its excitation is ideally suited for the 407 nm spectral line of the krypton laser or the 408 nm violet laser diode. BP Fluor 405 alkyne triTEA reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker. A probe for copper-less detection (BP Fluor 405 DBCO) is also available for application where the presence of copper is not acceptable.

BP Fluor 430 DBCO
0 ImagesCat. No.: HY-W800699CAS No.: 2644752-85-0BP Fluor 430 DBCO reacts with azides via a copper-free click chemistry reaction to form a stable triazole and does not require a Cu-catalyst or elevated temperatures. In applications where the presence of copper is a concern, BP Fluor 430 DBCO is an ideal alternative to copper requiring fluorescent alkynes. BP Fluor 430 is a bright, photostable, green-fluorescent probe optimally excited near its absorption maximum at 432 nm. Its emission peak at 539 nm is pH independent over a wide pH range. BP Fluor DBCO reagent is not suitable for staining intracellular components of fixed and permeabilized cells due to high backgrounds.
