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.

NIR-BG2
0 ImagesCat. No.: HY-165424CAS No.: 3036456-18-2NIR-BG2 is a fluorescent indicator targeting senescence-associated β-galactosidase (SA-β-Gal). NIR-BG2 contains a hemicyanine fluorophore caged by SA-β-Gal; cleavage of its β-galactosyl group by SA-β-Gal generates an electrophilic quinone methide, which can form covalent bonds with adjacent proteins to achieve long-term signal retention. NIR-BG2 activates a near-infrared fluorescent signal upon recognition of SA-β-Gal. NIR-BG2 can be used for non-invasive in vivo imaging of cellular senescence in mouse xenograft models. The excitation/emission wavelengths are 675/708 nm.
