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.

closed-HMRG
0 Imagesclosed-HMRG is an HMRG (HY-D2379) with a closed spiro-ring structure. HMRG is a fluorescent dye, which serves as the fluorescent active product generated by enzyme-activated fluorescent probes targeting proteases and glycosidases. Its detection mechanism relies on the intramolecular spirocyclization equilibrium: HMRG itself exists in an open non-spirocyclic structure under physiological pH, which maintains a conjugated π system and produces strong fluorescence; whereas its probe precursors (such as Leu-HMRG, Ac-GlyPro-HMRG and βGal-HMRG) exist in a closed spirocyclic form and show no fluorescence due to the disruption of the π-conjugated system; when the target enzyme cleaves the substrate fragment linked to the probe precursor, the closed spirocyclic structure converts to the open structure of HMRG, restoring the conjugated system and generating a strong fluorescent signal. Its detection wavelength is Ex/Em = 501/524 nm.
