Culturing cells for the commercial production of proteins for diagnosis and therapy is a costly and time consuming process. The equipment required is expensive, and production cost are high. In order to provide commercially viable processes it is desirable to use cell lines which produce large quantities of product with each production run. However, most cells do not produce large quantities of desired product per se either because they do not produce a large quantity of product per unit of time (specific productivity) or because they do not survive long enough in the culture medium (time). Here, we identified that addition of a valproic acid compound to the culture medium increases overall (batch) yield and titer. More importantly, compared to the widely used sodium butyrate, batch yields using a valproic acid compound as a medium additive are significantly higher.
