The Chinese hamster ovary (CHO) cell line is currently the most important mammalian production cell line for therapeutic proteins. The aim of this study was to use the proline auxotrophy of the CHO cell line as a selection system for the production of recombinant proteins. The gene of the enzyme pyrroline-5-carboxylate synthetase (P5CS), one key enzyme of proline synthesis, was used as a selection marker. Using the CHO-S cells, selection times and expression levels comparable to those of antibiotic selection with neomycin or hygromycin B could be reached. Expressing the green fluorescent protein (GFP), three different monoclonal antibodies (anti-CD303, anti-CD14, anti-Biotin) in a two-vector strategy in combination with a zeocin selection o...
