mass spectrometry assay peptide mass fingerprinting assay ERO:0001668 A mass spectrometry assay that measures the absolute mass of the cleaved peptides derived from an unknown protein of interest. These masses are then compared to values for known protein sequences to identify the unknown protein. protein fingerprinting Janos Demeter https://sourceforge.net/p/obi/obi-terms/725/ Chris Stoeckert PMF url:http://en.wikipedia.org/wiki/Peptide_mass_fingerprinting peptide mass fingerprinting assay metadata complete
