General description

Fluorescein isothiocyanate–dextran is an anionic fluorescent probe. The carboxyl group provides the negative charge, which improves the overall permeability of the molecule. It is supplied as a yellow powder that is freely soluble in water and electrolyte solutions. Fluorescein isothiocyanate–dextran is insoluble in most organic samples such as ethanol, methanol, acetone, and chloroform., however, it dissolves in DMSO, formamide, and a few other polar organic solvents.

Application

Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.
Fluorescein isothiocyanate–dextran has an application of cell analysis, Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals. FITC-dextrans are primary source of studying permeability and transport in cells and tissues and can also be a tool for permeability studies of other materials.

Phosphatidylcholine and phosphatidylcholine-derived metabolites exhibit anti-inflammatory properties in various stress conditions. We hypothesized that dietary phosphatidylcholine may potentially function as an anti-inflammatory substance and may decrease inflammatory activation in a chronic murine model of rheumatoid arthritis (collagen-induced arthritis). The experiments
