METHOD FOR PRESERVING BIOLOGICAL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a method for preserving a biological component immobilized without freezing in a medium consisting essentially of water under mild conditions to a biological component of normal temperature and normal pressure.

SOLUTION: The method for preserving a biological component comprises mixing a water-soluble polymer solution into which a biological component is dispersed with a water-soluble compound solution to form a three-dimensional crosslinked product and preserving the biological component in the state of the three-dimensional crosslinked product. Preferably the water-soluble polymer is a polymer containing a phosphorylcholine group and a phenylboronic acid group and the water-soluble compound is a compound containing a polyfunctional hydroxy group.
