The Effect of Dissolved Oxygen (DO) Concentration on the Glycosylation of Recombinant Protein Produced by the Insect Cell-Baculovirus System, F. Zhang, M.A. Saarinen, L.J. Itle, S.C. Lang, D.W. Murhammer, R.J. Linhardt, Biotechnology & Bioengineering, 77, 219-224, 2002.
The effect of dissolved oxygen concentration on human secreted alkaline phosphatase (SEAP) glycosylation by the insect cell-baculovirus expression system was investigated in a well-controlled bioreactor. Oligomannose-type N-linked glycans (i.e., Man2 to Man6 and Man3F) were present in SEAP produced by Spodoptera frusiperda Sf-9 (Sf-9) and Trichoplusia ni BTI-Tn-5B1-4 (Tn-5B1-4) insect cell lines. The relative amounts of the most highly processed glycans (i.e., Man3F and Man2 in the SEAP from Sf-9 and Tn-5B1-4 cells, respectively) were significantly higher at 50% of air saturation than at either 10% or 190% of air saturation. That is, glycan processing was inhibited at both low and high dissolved oxygen concentrations.;
