Growth curve for the CHO-s cells transfected with recombinant plasmids harboring either wild-type or codon-optimized hIFN-β sequence in comparison with the untransfected one, at transfection day (time 0) and 24, 48, and 72 h after transfection. Untransfectd cells showed higher proliferation rate in comparison with the transfected cells (** P < 0.01). CHO-s, suspension adapted Chinese hamster ovary; hIFN-β, the recombinant human interferon beta.
