 A screening platform to evaluate whether novel genes of interest, (identified from a SWATH comparative proteomics dataset1) increase antibody yield in Chinese hamster ovary cells that stably express a monoclonal antibody (mAb), is presented. Although there has been recent progress in the understanding of mAb production processes in CHO cells, 2 3, there is a need for further understanding of CHO cell biology so that this industrially relevant cell line can be engineered and optimised for the production of next generation antibodies utilising new bioreactor formats (e.g. perfusion). It is envisaged that data generated from these experiments will support some of the rational engineering strategies of the future, enabled by advanced technologies such as CRISPR-Cas9 4.
