HUMAN CELL STRAINS FOR PROTEIN PRODUCTION, PROVIDED BY SELECTING STRAINS WITH HIGH INTRACELLULAR PROTEIN AND MUTATING WITH CARCINOGENS

摘要

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.
