Use of pectic polysaccharides for cryopreservation of biological objects

Abstract

The protectant activity of pectic polysaccharides derived from various plants was studied on Saccharomyces cerevisiae yeast-like fungi, human blood platelets and leukocytes, and the antihemolytic action of the same compounds was studied on red blood cells. The feasibility of cryopreservation of biological objects in the environment of pectic polysaccharide- containing cryoprotectant solutions was demonstrated.
