Native Mass Spectrometry

Insight into drug Interactions

  • Affinity
  • Stoichiometry
  • Competition versus allosteric and orthosteric ligands
  • Cooperativity
  • Stability
Targets characterization
  • Intact mass
  • Purity/Homogeneity
  • Post-translational modifications
  • Detection of fortuitous ligands
  • Oligomerization state and its molecular
Biologics and biosimilars
  • Fab-arm exchange (FAE)
  • mAb / Ag binding measurement
  • Measure the drug-to-antibody ratio (DAR) for antibody drug conjugates (ADC).
  • CCS (collisional cross-section) measurement by IM-MS (ion mobility)

Over the last 20 years, NovAliX has routinely used native MS. Our extensive track record of complex studies includes proteins, biologics, nucleic acids, lipids and sugars.

This fast and reliable technique can provide both qualitative and quantitative information.

All these data provide key elements to understand drug interaction modes. The NovAliX MS platform is also designed to support screening, including fragment libraries.

Native MS: an ‘ESI’ way to support structure- and fragment-based drug discovery.
