Impact of Excipients on Viscosity

Excipients are a substance that is often added to protein formulations to serve as a medium for the proteins or active substance in the formulation. While commonly perceived as inert and just a supplement to improve the formulation or become a diluent, adding excipients have sometimes created a reaction of the ingredients in the formulation and according to the NPS Medicinewise article*, such reactions have resulted in various reactions in patients as well.

Latest Release & Upcoming Events

In the upcoming weeks, we are proud to announce the release of our latest application note regarding concentration dependence in protein viscosity. In this app note, Dr. Stacey Elliott gathered viscosity data for Bovine Gamma Globulin (BgG) formulations over the full concentration range, including therapeutic levels ≥ 100 mg/mL, using the VROC®Initium. The solution buffer included sucrose which is a common additive to enhance stabilization during freeze-drying and storage. Relative viscosity versus concentration curves were fit with the Ross-Minton equation which is a frequently used analysis tool for protein formulations.
