The strategies described here can improve the efficiency and analyte recovery of chromatographic methods used to characterize monoclonal antibodies and antibody– drug conjugates.

Biotherapeutics have become the hottest topic in pharmaceutical research over the past decade. With the increased interest in biotherapeutics, there has been a concomitant increase in new analytical methods for characterizing these large, complex molecules. This installment of “Column Watch” discusses advances in “bottom-up” analysis of monoclonal antibodies, while highlighting the role and importance column chemistry still plays in developing highly selective high-performance liquid chromatography (HPLC) methods for peptides.

This installment of “Column Watch” discusses advances in “bottom-up” analysis of monoclonal antibodies, while highlighting the role and importance column chemistry still plays in developing highly selective high-performance liquid chromatography (HPLC) methods for peptides.

New strategies for “bottom-up” analysis of therapeutic proteins, using faster enzymes, new buffer systems, and optimal column chemistries, enable analysts to perform these studies much faster and with fewer artifacts.

The 47th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2018), chaired by Norman Dovichi, was held from 29 July to 2 August in Washington, D.C., USA. This instalment of “Column Watch” covers some of the highlights observed at the symposium. In addition, trends and perspectives on future developments in HPLC noted from the conference are presented.
