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.

Aqueous environments in living cells are crowded, with up to >50 wt% small and macromolecule-size solutes. We investigated quantitatively one important consequence of molecular crowding--reduced diffusion of biologically important solutes. Fluorescence correlation spectroscopy (FCS) was used to measure the diffusion

The cryopreservation of oocytes is valuable for the preservation of women's fertility and might also be an interesting tool to preserve animal genetic biodiversity but it is not often used because of the very poor fertility recovered after thawing, especially

This study was designed to evaluate vitrification procedures for in vitro matured bovine oocytes for efficient blastocyst production after warming, IVF and culture. A second goal was to replace serum as the macromolecular component of the vitrification solution, without compromising

Macromolecular crowding has been proposed as a mechanism by means of which a cell can sense relatively small changes in volume or, more accurately, the concentration of intracellular solutes. According to the macromolecular theory, the kinetics and equilibria of enzymes

The non-ideal properties of solutions containing high concentrations of macromolecules can result in enormous increases in the activity of the individual macromolecules. There is considerable evidence that macromolecular crowding and confinement not only occur in cells, but that these are
