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.

LysoAIE2
0 ImagesCat. No.: HY-D3120CAS No.: 2246946-53-0LysoAIE2 is a Fluorescent probe for lysosomal viscosity detection and live-cell imaging. Its detection mechanism relies on the aggregation-induced emission effect: it exhibits only weak fluorescence in non-viscous media; in viscous environments, restricted intramolecular motion inhibits non-radiative energy dissipation pathways, thereby significantly enhancing fluorescence intensity. It achieves specific targeting of lysosomes through the proton acceptor property of its indole ring structure, while its hydroxyl group endows it with excellent water solubility. This probe is basically unaffected by microenvironmental polarity and pH within the range of pH 4.0 to pH 8.0, which avoids interference from these factors in viscosity measurement. LysoAIE2 has an emission wavelength of 570 nm. It can be used to monitor lysosomal viscosity changes during processes such as Dexamethasone (HY-14648)-induced lysosomal migration and starvation-induced mitophagy in live cells; at concentrations up to 40 μM, cell viability remains above 80%, demonstrating excellent biocompatibility.
