ACG focuses on providing routine, investigative, and in-depth characterization as well as proteomics analyses of AbbVies biologics to support product and process development for early-phase, late-phase, and commercial programs using liquid chromatography mass spectrometry (LC-MS), spectroscopy, and various other biophysical characterization assays. Responsibilities: Independently perform LC-MS analyses (e.g., intact, reduced, sub-unit, peptide mapping, and disulfide bond mapping) of AbbVies biologics to provide sequence verification, post-translational modification profiles, sequence variant levels, and disulfide bond profiles.
