方法である。The present invention was completed based on this knowledge, and has an M/G ratio of 0.2-1.5 and a 1% solution of 10-1500 cp (
001 of sodium alginate) at 25°C
~2% solution to which one or more of a chelating agent and particulates such as animal cells, intracellular organelles, plant cells, plant somatic embryos, starch, glass beads, activated carbon, silica gel, and ion exchange resins are added. This is a method for producing a gel having an air bubble, which is characterized by molding it into an appropriate shape using calcium ions.
微粒子の大きさとしては0.1〜200μl程度がよい
。The size of the fine particles is preferably about 0.1 to 200 μl.

しているものである。The dry gel of the present invention has fine particles scattered in the gel,
An air bubble is formed from the fine particles toward the center of the gel, and the air bubble is filled with liquid such as water or a culture medium.
本発明においては、特定の物性をそなえたアルギン酸ナ
トリウムが使用される。In the present invention, sodium alginate with specific physical properties is used.
一般に、アルギン酸はD−マンヌロン酸(M)とL−グ
ルロン酸(G)とから構成されていて、両者の成分比(
M/G比)が物性に大きな影響を与えている。Generally, alginic acid is composed of D-mannuronic acid (M) and L-guluronic acid (G), and the ratio of the two components is (
M/G ratio) has a great influence on physical properties.
