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.

Nile-TPA
0 ImagesCat. No.: HY-D3101Nile-TPA is a fluorescent probe for polarity detection, which can be used for lipid droplet targeting, cell polarity analysis, in vivo polarity imaging, and blood polarity monitoring in circulating tumor mouse models. The detection mechanism of Nile-TPA relies on the dual intramolecular charge transfer (ICT) effect generated by the electron-donating triphenylamine and Nile Red moieties and the electron-withdrawing carbonyl group; this probe emits strong red fluorescence in a low-polarity environment, and as polarity increases, the fluorescence intensity decreases and a red shift occurs due to changes in the excited-state dipole moment. In spectral tests, its excitation wavelength is 540 nm, and the emission wavelength varies in the range of 550-800 nm depending on solvent polarity; for cell, zebrafish and mouse imaging, Ex/Em = 561/570-620 nm, and for in vivo mouse imaging, Ex/Em = 560/620 nm.

PNO1
0 ImagesCat. No.: HY-D3351CAS No.: 2668963-61-7PNO1 is a fluorescent probe for pulmonary fibrosis detection. The detection mechanism of PNO1 relies on sensing upregulated nitric oxide (NO) in the pulmonary fibrosis (PF) microenvironment. PNO1 contains an aniline group that reacts with NO or its derivatives under acidic conditions to form an N-nitrosylated intermediate, which is subsequently converted into a diazonium salt and undergoes deamination, eliminating the intramolecular electron transfer quenching effect and triggering a fluorescence turn-on response. The excitation wavelength of PNO1 includes 545 nm in in vitro solution studies, while an excitation range of 520-550 nm is used for cell, tissue and in vivo imaging; its emission wavelength centers at 572 nm in the unreacted state, and shifts to 559 nm with enhanced fluorescence intensity upon binding to NO. PNO1 can be used for pulmonary fibrosis research.
