CELL STRAIN CONDITIONED TO PROTEIN- AND LIPID-FREE CULTURE MEDIUM, METHOD FOR PRODUCING SAME, AND CULTURE MEDIUM

摘要

Provided is a cell strain derived from a Chinese hamster ovary (CHO) which can be used in producing stable gene recombinant proteins without worries about stability, can be proliferated while floating, and can be cultured at a low unit cost. Moreover, provided are a method for conditioning a CHO cell to a protein- and lipid-free culture medium and a culture medium using the same. In the protein- and lipid-free culture medium which does not contain an extrinsic growth factor, a cell derived from a CHO cell and conditioned to the protein- and lipid-free culture medium can be proliferated while floating.;COPYRIGHT KIPO 2015
