Analysis of oxidative protein modifications. Proteins are oxidized by ROS. Subsequent molecular changes can be analyzed for individual proteins, peptides or modified amino acids. Depending on the choice of analytes, different analysis techniques are available. Among the presented methods, mass spectrometry is the most accurate technique and its application shall be further increased for biological samples to advance the knowledge regarding protein oxidation.
