High molecular weight sucrose-polymers formed by copolymerization of sucrose with epichlorohydrin. The molecules are highly branched and the high content of hydroxyl groups leads to very good solubility in aqueous media.

Ficoll^® PM400 is a synthetic neutral, highly-branched hydrophilic polymer of sucrose with an average molecular weight of 400 000. It has long been used to form density gradients for separating and isolating eukaryotic cells, organelles and bacterial cells, as a stabilizing agent, and as a preparation medium for isolating mononuclear cells. Applications can also be found in defined culture media, nucleic acid hybridization, electrophoresis, and immunological studies.

It is delivered as a spray-dried powder and is therefore readily soluble in aqueous media when it is added slowly with concomitant stirring. Any lumps formed during this procedure will dissolve fairly quickly. Concentrations up to 50% (w/v) can easily be attained

Used in the formation of density gradients for the separation and isolation of eukaryotic cells, organelles, and bacterial cells, as a stabilizing agent and as a separation medium for the isolation of lymphocytes.
It also has applications in defined culture media, nucleic acid hybridization, electrophoresis, and immunological studies.
Used for gradient centrifugation in all types of centrifuge rotors and for separation at unit gravity.
