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.

MitoAIE1
0 ImagesCat. No.: HY-D3119CAS No.: 2246946-49-4MitoAIE1 is a Fluorescent probe for mitochondrial viscosity detection. MitoAIE1 contains a pyridinium structural unit, which endows it with mitochondria-targeting specificity. The detection mechanism of this probe is based on aggregation-induced emission (AIE): in low-viscosity media such as PBS buffer, intramolecular rotation leads to non-radiative energy dissipation, resulting in only weak fluorescence; however, in high-viscosity environments such as the mitochondrial matrix or the vicinity of the inner mitochondrial membrane, such intramolecular motion is restricted, thereby significantly enhancing its fluorescent signal; in addition, this probe is not interfered by changes in microenvironment polarity and pH. Its emission wavelength is 625 nm, with absorption peaks at 325 nm and 450 nm; when transferred from low-viscosity PBS to high-viscosity 99% glycerol, its fluorescence intensity at 625 nm can be increased by 38-fold. It can be used to monitor changes in mitochondrial viscosity during processes such as Stauroporine (HY-15141)-induced apoptosis and starvation-induced mitophagy in live cells, and has good biocompatibility.
