  • Method for producing a recombinant protein using a cell line adapted to a protein-free and lipid-free medium
    Patent number: 9340814
    Abstract: A method for producing a recombinant protein includes steps of: (a) culturing a transformed cell in a protein-free and lipid-free medium containing no exogenous growth factors, in which the transformed cell is produced by transfecting a cell of a cell line derived from Chinese Hamster Ovary (CHO) cells, the cell line is adapted to a protein-free and lipid-free medium, and the cell is capable of proliferating in a suspended state in a protein-free and lipid-free medium containing no exogenous growth factors, with a vector containing a gene coding for the protein to be produced under the control of a promoter operable in the cell, and (b) recovering the protein produced by the transformed cell.
