  • Reproducible safety and efficacy profiles for biotherapeutic proteins require manufacturers to produce products with consistent tertiary structures
  • Methods for determining changes in higher order structure are invaluable for the assessment of product quality
  • In this work, Waters SYNAPT® G2 HDMS™ is used to characterize biotherapeutic protein tertiary structures and data from orthogonal analytical techniques is applied to corroborate the IMS results
  • Cross-sectional areas measured by IMS method are in good agreement with those calculated using the MOBCAL computations
