The present invention relates to a protein production accelerating agent that has enabled to largely increase the produced amount of a desired protein by adding polysaccharides to a medium for animal cells containing a serum or serum alternative, and a production method of a protein using a medium containing the protein production accelerating agent.

Enhancing ingredients for protein production from various cells

This invention provides an anti-allergic substance that effectively inhibits allergic symptoms by inhibiting production of the IgE antibody associated with the development of allergies. Anti-allergic substances, pharmaceutical products (i.e., anti-allergic agents), and food (i.e., food with health-promoting benefits) containing strawberry-derived glyceraldehyde-3-phosphate do not cause side effects such as those caused by steroids, and such substances can be consumed through daily meals and can alleviate allergic symptoms.

Anti-allergic substance, anti-allergic agent, and food

A novel human cell strain enabling the continuous production of a desired protein with high efficiency, comprising a novel human cell strain established by transforming a human cell strain whose total intracellular protein weight is 0.1 to 1 mg per 1,000,000 cells; with the novel human cell strain being further characterized in that after a gene encoding a desired protein is transfected into it, the transfected cell is subsequently cultured.

Human cell strains for protein production, provided by selecting strains with high intracellular protein and mutating with carcinogens
