Claims4
An agent for preserving a biological component, comprising a hydrogel, the hydrogel comprising a crosslinked product formed from polyvinyl alcohol and a modified hyaluronic acid having substituents capable of reacting with the hydroxyl groups to form a crosslinked structure;
- wherein
- the modified hyaluronic acid has disaccharide units and is represented by the following formula (1):
- wherein R1 represents a direct bond or a divalent group;
- and
- wherein the hydrogel further comprises unmodified hyaluronic acid.
A kit for preparing an agent for preserving a biological component, the kit comprising a first agent containing polyvinyl alcohol and unmodified hyaluronic acid and a second agent containing a modified hyaluronic acid having substituents capable of reacting with the hydroxyl groups to form a crosslinked structure;
- wherein
- the modified hyaluronic acid has disaccharide units and is represented by the following formula (1):
- wherein R1 represents a direct bond or a divalent group.
