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 acid
0 ImagesCat. No.: HY-D2747CAS No.: 1638784-10-7BP Fluor 405 acid is a water-soluble, blue-fluorescent dye that is 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 conjugates are pH-insensitive from pH 4 to pH 10. The carboxylic acid of BP Fluor 405 is a reagent of choice for the preparation of custom activated esters that often are not commercially available. Examples of such activated esters include sulfo-NHS, TFP (2,3,5,6-Tetrafluorophenol), and STP (4-Sulfo-2,3,5,6-Tetrafluorophenol, Sodium Salt). Another common application for the non-activated carboxylic acid is peptide modification during solid phase synthesis, which usually requires in-situ activation with peptide coupling regents, e.g. HATU. BP Fluor 405 acid is also often used for control experiments, and for calibration.

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.
