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.

CDg16
0 ImagesCat. No.: HY-D3197CDg16 is a selective fluorescent dye targeting SLC18B1 (λabs/λem=458/544 nm) that is actively transported into lysosomal vesicles of activated macrophages independent of the endocytic pathway. CDg16 enables highly specific vesicle localization in live cells. CDg16 exhibits no cytotoxicity and accurately distinguishes activated M1 and M2 subsets from different origins. CDg16 shows low background staining in non-activated cells and normal organs, making it suitable for time-lapse imaging. In preclinical animal models of inflammatory sites, atherosclerotic plaques and liver inflammation, CDg16 allows visualization of activated macrophages. CDg16 can be used to study inflammation-related diseases and atherosclerosis.
