A new procedure developed by a research group at the Faculty of Science and Technology of the University of Debrecen (FST, UD) may open up new avenues and provide a roadmap for future mass spectrometry analyses. This new testing method significantly reduces the time and cost of mass spectrometry measurements of proteins both in the pharmaceutical industry and protein research. The publication that summarizes the scientific finding has appeared in one of the most prestigious international chemistry journals, Angewandte Chemie.
