Polysucrose 400 is a synthetic high molecular weight polymer made by co-polymerization of sucrose and epichlorohydrin. The molecules have branced structure with a high content of hydroxyl groups giving a good solubility in aqueous media. The product is similar to Ficoll 400® from GE Biosciences. Polysucrose 400 is readily soluble in aqueous solutions when added slowly with stirring. Concentrtations up to 50% (w/v) can easily be prepared.
