General description

Ficoll® PM70, a high molecular weight branched polysaccharide polymer, is believed that they do not contain any ionized groups. This sucrose-polymer is formed by the copolymerization of sucrose with epichlorhydrin.

Application

Ficoll® PM 70 has been used:
  • as a macromolecule in a comparative study to evaluate its effect in vitrification solutions
  • as a supplement in the vitrification solution for the vitrification procedure of oocytes
  • as a component of low serum medium for human lung fibroblast cell culture to promote a crowded environment

Biochem/physiol Actions

Ficoll is commonly used as a macromolecular constituent of vitrification solutions. Due to their dense branching, Ficolls also serve as ideal, nearly spherical molecular crowding agents.
FicollTM PM 70 is used as a macromolecular crowding agent in studies of cell volume signaling and protein refolding.It may be used in tissue engineering and macromolecular conformation research for the development, evaluation, and use of macromolecular crowding (MMC) systems and configurations. Ficoll PM-70 can also be used in vitrification research.

Protocols

Ficoll>sup>® 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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
