    Experimental workflow of the study, promoter characteristics and vector designs. ( A , B ) Schematic representation of the workflow: Promoter strengths in the transient expression context were quantified using dual luciferase assay and flow cytometry analysis. ( A ) All nine promoters were compared based on luciferase activity in CHO cell variants and HEK-293T cells (Experimental setting 1). To corroborate the dual luciferase reporter findings, one weak and three relatively strong promoters were cloned into the dual fluorescence reporter system and further investigated by flow cytometry analysis (Experimental setting 2). ( B ) The activity of five relatively strong promoters selected and prioritized from ( A ) was evaluated in stable transfectants of CHO-DG44 suspension cells by dual luciferase assay. Further experiments were performed to analyze the expression of Fluc and Rluc genes, as well as the copy number of Rluc and DHFR genes.

In the dual luciferase reporter system, the variable promoter (CMV-mIE) was replaced by SV40, HSV-TK, <t>EF1α,</t> <t>EFS,</t> UBC, PGK, CHEF1α and CAG promoters. In the dual fluorescent reporter system, the variable CMV-mIE was replaced by SV40, HSV-TK and CHEF1α promoters.
