A fructose containing cell culture medium has the advantage of low lactate production and a small pH change, leading to cell and product stability. But, not all cell lines grow well in the medium, and the fructose transporter, GLUT5, is related to it . Thus, we developed an efficient production system of recombinant proteins by metabolic control and co-expression with GLUT5 in a fructose-based medium . In this report, the availability of the GLUT5 co-expression system was indicated in CHO-K1 and the human cell line, SC-01MFP .
