  • Protein Cleavage at Aspartic Acid Using Chemical Reagents
    Publication number: 20080318262
    Abstract: The present invention relates to the methods of identifying and quantifying polypeptides in a given sample by mass spectrometric analysis. More specifically, the invention provides the methods for sample preparation for proteomic analysis: the methods for the fragmentation of proteins into peptides with the specific cleavage rule (cleavage at amino-terminal or carboxyl-terminal of aspartic acid), which are suitable for the analysis by mass spectrometry apparatus.
