Abstract
Official abstract text for this publication.
Disclosed are an anti-ice nucleation activator comprising a purine base or a purine base-containing polymer, and an antifreeze liquid comprising the anti-ice nucleation activator and water; a method for improving the anti-ice nucleation activity of a biological material, the method comprising bringing the anti-ice nucleation activator into contact with the biological material; and a method for preserving a biological material, the method comprising bringing the anti-ice nucleation activator into contact with a biological material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for improving anti-ice nucleation activity of a biological material, the method comprising the steps of bringing an anti-ice nucleation activator comprising a purine base-containing polymer into contact with a biological material and cooling the biological material, wherein the purine base-containing polymer is a polydeoxyadenylic acid. 2. The method according claim 1 , wherein the anti-ice nucleation activator is liquid. 3. The method according to claim 1 , wherein the anti-ice nucleation activator further comprises water. 4. The method according to claim 1 , wherein the biological material is cooled to 0° C. or lower in the cooling step.
