The cryoprotective action of glycerol on the strain L cells was studied. Glycerol, even when present only in the cell interior or only in the surrounding medium, apparently furnishes the cells cryoprotection to some extent, but glycerol in the cell interior seems to be more effective than in the medium. Its presence both in the cell interior and in the medium is a requisite for perfect protection against freezethawing injury.
