GeneArt® Genes to Cell Lines
 | Generation of High-Performance Cell Lines With Stable Expression of Your ProteinTo generate stable cell lines, the GeneArt® Genes-to-Cell Lines Service uses a combination of advanced technologies: expression-optimized genes subcloned into our proprietary vector that was developed in-house. |
Our process is designed for enhanced transgene integration, transgene expression, and genetic stability of cell lines—including protein productivity characteristics—even when scaled up for production of large amounts of protein. Optimized selection strategies and culture conditions ensure high protein yields (see below).

Gene optimization can greatly increase protein expression levels
Comparison of protein expression from stable cell lines transfected with wild type and optimized gene. Stable cell lines expressing a secreted human protein were generated by transfection with a recombinant expression vector containing either a wild type gene (lanes 1, 2) or a GeneArt® GeneOptimizer®-improved gene (lanes 3, 4). The four cell lines were grown in parallel using standardized conditions. Recombinant protein was immunoprecipitated from identical volumes of conditioned medium and analyzed on a Coomassie-stained gel and by western blot. The concentration of recombinant protein in the conditioned media was quantified by ELISA. | )
