Polysaccharides circumvent the high osmotic strength issues that arise with using sucrose solutions. The most common polysaccharide medium used in Ficoll®. Ficoll is produced by the polymerization of sucrose molecules with epichlorohydrin to give a polysaccharide with the average molecules weight of 400,000. Ficoll solutions below 20%(w/v) have a density of 1.07g/cm3 and are considered osmotically inert. The main disadvantage is Ficoll solutions are more viscous than comparable sucrose solutions.
