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.

TPE-SQ5
0 ImagesCat. No.: HY-D3094CAS No.: 2687198-42-9TPE-SQ5 is a ratiometric Fluorescent probe for hypochlorite (ClO-) detection with a limit of detection of 5.6 nM. TPE-SQ5 exhibits high selectivity and high sensitivity towards ClO-. TPE-SQ5 can be oxidized by ClO- to form an epoxide, which quenches its deep red fluorescence; subsequently, the epoxide decomposes into a hemicyanine and a sulfonic acid-substituted oxindole, producing blue-green fluorescence to achieve a ratiometric response. TPE-SQ5 can form nanoparticles with Pluronic F-127 via the nanoprecipitation method, and these nanoparticles possess cell permeability. TPE-SQ5 has unique Ex/Em spectra in different solvents and nanoparticle forms, with emission peaks at 643 nm (380 nm excitation, 95% H2O/THF), 631 nm (564 nm excitation, DMSO), 652 nm (536 nm excitation, THF) and 630 nm (524 nm excitation, nanoparticles); the Ex/Em settings used for cell imaging are 488/550-650 nm (red channel) and 405/450-550 nm (green channel).
