Keep It Real - with Native Protein MS

We present a novel workflow for native MS, using a robust and sensitive LC/MS method using standard LC flow for native protein analysis. Most of the native MS analyses are using a nano-electrospray approach, which faces significant challenges in handling as well as throughput.

The workflow comprised the Agilent 1290 Infinity II LC, the AdvanceBio SEC column, the 6545XT AdvanceBio LC/Q-TOF, and MassHunter BioConfirm software. Examples from ligand-binding proteins, MAb’s as well as non-covalent complexes will be shown using standard-flow conditions, demonstrating charge-state distribution previously only observed with nano-spray.

We have also utilized the Ion Mobility Q-TOF system to determine the Collision Cross Section (CCS) values of the native protein molecules and the result for different mAb classes and biosimiliars will be shown.
