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.

Ac-MtFluNox
0 ImagesCat. No.: HY-D3123Ac-MtFluNox is a mitochondria-targeted Fluorescent probe that can be used for the selective detection of labile Fe (II). Ac-MtFluNox can enter living cells, where intracellular esterases cleave its acetyl protecting group to generate activated MtFluNox. Ac-MtFluNox functions through an Fe (II)-mediated deoxygenation mechanism of its amine N-oxide group, which eliminates the fluorescence quenching effect and oxidizes Fe (II) to Fe (III) to deplete the catalytically active Fe (II) pool. A FITC filter set (excitation 465-500 nm, emission 516-556 nm) is used for live-cell imaging. Ac-MtFluNox can be applied to studies related to myocardial ferroptosis.

HMRef-αMan
0 ImagesCat. No.: HY-D3187CAS No.: 2484831-02-7HMRef-αMan is a substrate-based green fluorescent probe (Ex/Em=465 nm/515 nm) targeting MAN2C1 (α-mannosidase). HMRef-αMan can be specifically cleaved by MAN2C1 to generate a highly fluorescent product, which thus gets activated to produce green fluorescence in malignant breast tissues, benign lesions and living cancer cells. The signal intensity of HMRef-αMan is directly correlated with MAN2C1 activity, and it can effectively detect tiny breast cancer lesions with a diameter of less than 1 mm. When used in combination with the red-emitting γ-glutamyl transpeptidase (GGT) probe gGlu-2OMe SiR600 (HY-D3188), HMRef-αMan enables precise optical differentiation of breast tissue types via a dual-color imaging strategy. HMRef-αMan has been widely used in the research of breast diseases such as breast cancer, fibroadenoma, phyllodes tumor and various types of papilloma.
