Cryopreservation

Cryopreservation is a process employed for the preservation of biological matter such as cells, tissues and organs. The preservation is performed at low temperatures, typically at liquid nitrogen temperature at −196 °C. The application scope of cryopreservation is very large spanning from preservation of cells or organs to cryosurgery, blood transfusion and in vitro fertilization (1). The process requires the use of suitable media involving compounds or derivatives, also called cryoprotectants. These needs to be of low toxicity, have a strong anti-freezing capacity and a good post-thawing performance.

Products

In addition to the catalogue-listed polysaccharide derivatives targeted to cryopreservation we can also provide also a range of low molecular weight derivatives with potential cryopreservative capacity. This includes:

  • Sucrose derivatives: Sucrose sulfate, DEAE-sucrose, CM-sucrose and Q-sucrose.
  • Sorbitol derivatives: Sorbitol sulfate, DEAE-sorbitol, CM-sorbitol and Q-sorbitol.

Please contact us if you are interested in any of the compounds listed above. You can read more about our customised products here.
