Protein variation degree detection method and application thereof

摘要: The invention provides a protein variation degree detection method, which comprises the following steps: using triple quadrupole mass spectrometer for spectrum quantitative determination of peptide fragments same target at different physiological and pathological periods; according to result, classifying protein; determining degreeaccording proportion relation types protein. method is brand new belongs pioneering invention, enables each fragment in protein, so that processes biological cells can be reflected on fragments.
