Background: Pectins have a large number of active -OH and -COOH groups (3), suggesting the presence of this group of substances specific cryoprotective effect.
Objective: This research is aimed at studying the ability of pectins (zosteran, apple pectin АU-701, E-440) to change the freezing temperature of glycerol, which can increase the effect in the cryopreservation of nuclear cells.
Methods: Using the cryoscopic method we studied the ability of pectins (zosteran, apple pectin AU-701, E-440) to change the freezing temperature of glycerol.
