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.

AldRed 588-A
0 ImagesCat. No.: HY-D3182CAS No.: 2252329-12-5AldeRed 588-A is a fluorescent labeling reagent and a substrate for aldehyde dehydrogenase (ALDH). AldeRed 588-A is metabolized by functionally active ALDH enzymes, thereby specifically labeling viable ALDHbright cell populations with red-shifted fluorescence. AldeRed 588-A supports one-step isolation and sorting of ALDH-expressing cells (including normal stem cells and cancer stem cells), and can be used in combination with green fluorophores for multicolor experimental applications. AldeRed 588-A is widely applicable to research related to various cancers such as bladder cancer, breast cancer, and head and neck cancer.

Mito-polarity
0 ImagesCat. No.: HY-D3086CAS No.: 1668565-72-7Mito-polarity is a mitochondria-targeted polarity probe. Mito-polarity can be used to detect mitochondrial polarity. The detection mechanism of Mito-polarity is based on an intramolecular charge transfer (ICT) system designed with a donor-π-bridge-acceptor (D-π-A) structure. Among them, the 467 nm green emission generated by the Coumarin (HY-N0709) structure is extremely sensitive to polarity changes, while the 642 nm red emission produced by the extended π-conjugation and ICT effect between the Coumarin and benzothiazine structures shows only a weak response, thus forming a ratiometric fluorescence response that is linearly correlated with solvent polarity. When Mito-polarity is excited at 405 nm in methanol, its excitation/emission wavelengths are Ex/Em = 405/467 nm and Ex/Em = 405/642 nm, with maximum absorption wavelengths of 426 nm and 561 nm.
