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.

NIR‐fluorescent ceramide
0 ImagesCat. No.: HY-D3198CAS No.: 2351937-34-1NIR-fluorescent ceramide is a neutral near-infrared (NIF) fluorescent probe (λem=650 nm) based on the C-bridged nitrobenzoxadiazole SCOTfluor core, which enables visualization of lipid metabolic processes such as sphingolipid trafficking. The emission signal of NIR-fluorescent ceramide increases significantly in liposomal environments. NIR-fluorescent ceramide acts as an intracellular trafficking tracer, localizing to regions surrounding the endoplasmic reticulum and Golgi apparatus within a short period, and then translocating to recycling lysosomes over a longer period, thus enabling real-time visualization of sphingolipid trafficking and biological lipid functions in living cells. NIR-fluorescent ceramide also generates metabolic uptake profiles and provides multiple metabolic readouts in human cancer cell lines.
