Collagen analysis with mass spectrometry

Mass spectrometry‐based techniques can be applied to investigate collagen with respect to identification, quantification, supramolecular organization, and various post‐translational modifications. The continuous interest in collagen research has led to a shift from techniques to analyze the physical characteristics of collagen to methods to study collagen abundance and modifications. In this review, we illustrate the potential of mass spectrometry for in‐depth analyses of collagen.
