A decay of fluorescence probe 1-anilino-8-naphtalene sulfonate (ANS) sorbed on low density lipoproteins (LDL) surface obtained from human plasma was described. It was demonstrated that on the LDL surface the ANS probe is allocated among two pools of molecules with the time of fluorescence decay 4-7 ns and 12-16 ns. One may conclude that 75-90% of the probe is connected with lipid LDL matrix.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008077 Lipoproteins, LDL A class of lipoproteins of small size (18-25 nm) and light (1.019-1.063 g/ml) particles with a core composed mainly of CHOLESTEROL ESTERS and smaller amounts of TRIGLYCERIDES. The surface monolayer consists mostly of PHOSPHOLIPIDS, a single copy of APOLIPOPROTEIN B-100, and free cholesterol molecules. The main LDL function is to transport cholesterol and cholesterol esters to extrahepatic tissues.

D005456 Fluorescent Dyes Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.
