This study integrates surface plasmon resonance-biomolecular interaction analysis (SPR-BIA) with mass spectrometry (MS) to enhance protein characterization. This combined biomolecular interaction analysis-mass spectrometry (BIA-MS) approach offers detailed insights into protein structure and interactions.

Area of Science:

  • Proteomics
  • Biochemistry
  • Analytical Chemistry

Background:

  • Proteomics relies on 2D electrophoresis and mass spectrometry for protein identification.
  • Analyzing complex protein mixtures generates data that raises questions about protein structure and function.
  • High-specificity methods are needed for analyzing biomolecular recognition and interacting partners.

Purpose of the Study:

  • To detail progress in using biomolecular interaction analysis-mass spectrometry (BIA-MS) for protein characterization.
  • To introduce biosensor chip mass spectrometry (BCMS) as a novel chip-based proteomics approach.
  • To demonstrate the combined use of SPR-BIA and MALDI-TOF MS for functional and structural protein analysis.

Main Methods:

  • Interfacing surface plasmon resonance-biomolecular interaction analysis (SPR-BIA) with matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry.
