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.

AM4-66
0 ImagesCat. No.: HY-D3385AM4-66 is a fluorescent dye used for cell membrane surface labeling. AM4-66 serves as a cell membrane surface marker and can label intact plasma membranes; when used sequentially with fluid-phase endocytosis markers such as fluorescent dextran, it does not stain dextran-positive intracellular structures that have detached from the cell surface, thus confirming that these internalized membranes no longer belong to the intact cell membrane surface (Ex/Em = 510/750 nm).
