Abstract
A novel class of nonpermeating cryoprotectants which, when mixed with certain known penetrating cryoprotectants, provide a useful medium for protection of living cells during a cryopreservation process. Algae-derived polysaccharides such as agarose and alginate are useful as nonpermeating cryoprotectants as they form a gel matrix when cooled, protect against ice crystal formation, and yield improved viability of cells when thawed.
