Research on new analytical methods for characterizing protein-based pharmaceuticals has been published in the journal mAbs by Gustavus chemistry major Matt Sorensen (’16), chemistry professor Dr. Dwight Stoll, and several collaborators (link to the full article here). The new methods developed at Gustavus, based on two-dimensional liquid chromatography, will enable more effective and efficient characterization of proteins and other biomolecules that are candidate treatments for diseases including cancer and arthritis. In the past few years the global use of such biotherapeutics has surpassed that of small molecule drugs, in spite of their complexity and the difficulty associated with characterizing them.
