Cryoprotectant and/or cryopreservant composition, methods and uses thereof

摘要: Cryoprotectants can be divided either by molecular weight (high-MW or low-MW) or by rate of penetration in the cell; ethanol, ethylene-glycol or methylacetamide which penetrate quickly or glycerol which penetrates more slowly.cryoprotectants such as mono-, oligo and polysaccharides, proteins and biopolymers that do not permeate the cell wall and/or the cytoplasmic membrane and offer extracellular cryoprotection at concentrations between 10 and 40% 1'4.
