General description

Ficoll® 400 is a non-ionic synthetic polymer of sucrose used for cell separation and organ isolation.


Suitable for
  • hybridization experiments to reduce non-specific binding of labeled probes to the membrane
  • preparation of DNA loading buffer (15% Ficoll®, 0.25% bromophenol blue and 0.25% xylene cyanol FF
  • separation of cells with similar density but different size (PBMC from human peripheral blood, bone marrow and umbilical cord blood)
  • producing density gradients to separate subcellular components
  • vitrification of cell and tissue samples.
  • to compare the effect of different perfusates on Hypoxic pulmonary vasoconstriction (HPV).
Used for cell separation and organelle isolation.

Features and Benefits

  • free from DNases, RNases, phosphatases and proteases
  • preserves functional and morphological integrity of the separated cells

Other Notes

A nonionic synthetic polymer of sucrose.

Ficoll® 400 for Gradient Centrifugation

Ficoll 400® is a highly branched polymer formed by the copolymerization of sucrose and epichlorohydrin. Ficoll 400® is completely non-ionic. Because of the abundance of hydroxyl groups, Ficoll 400® is very hydrophilic and extremely water-soluble.
