Optimal production of bispecific antibodies requires efficient and tailored co-expression and assembly of two distinct heavy and two distinct light chains. Here, we describe a novel technology to modulate the translational strength of antibody chains via Kozak sequence variants to produce bispecific antibodies in a single cell line. In this study, we designed and screened a large Kozak sequence library to identify 10 independent variants that can modulate protein expression levels from approximately 0.2 to 1.3-fold compared to the Wild-type sequence in transient transfection. We used a combination of several of these variants, covering a wide range of translational strength,…
