Ficoll 400 [20%] solution

Ficoll 400 is as a density gradient medium for the separation and isolation of eukaryotic cells, organelles and bacterial cells.
Ficoll 400 is a highly branched polymer formed by the copolymerization of sucrose and epichlorohydrin. It is completely non-ionic. Because of the abundance of hydroxyl groups, Ficoll 400 is very hydrophilic and extremely water-soluble.
