This book compiles articles from the journal Biomacromolecular Mass Spectrometry which covers research in the fields of biomacromolecules such as proteins, DNA, and other biopolymers studied with mass spectrometry and peripheric techniques. Cleavage and breakdown of the large molecules are often necessary for their investigation and, therefore, studies on the products are also of importance to the book. Biomolecular mass spectrometry has become a major analytical technique during recent years driving the biosciences forward at the same time. Research tends to be more and more interdisciplinary, and the journal attempts to bridge all biomacromolecules in an effort to enhance communication among scientists. This book publishes the Proceedings of the Annual Münster Conference on Single Cell and Molecule Analysis.
