Viscosity of mAbA (A), mAbB (B) and mAbC (C) solutions at 20°C in the presence of the indicated excipient. Dynamic viscosity of concentrated solutions of mAbA, mAbB and mAbC were determined using cone and plate rheometry at 20°C at a final protein concentration of 100 mg/mL in either 25 mM Na-acetate, pH 5.5 buffer alone or with the addition of 100 mM NaCl, 100 mM L-arginine.HCl or 200 mM trehalose.
