摘要
Methods to assess biological enzyme activity directly in a complex clinical sample. To such a sample, e.g., plasma, an exogenous synthetic peptide substrate for an enzyme present in the sample and to be assessed is added. The sample then undergoes mass spectrometric immunoassay (MSIA) to monitor the mass spectral profile of the immuno-purified exogenous synthetic peptide substrate directly from the sample. Using the resulting profile, parameters such as enzyme activity and effect of enzyme modulators, including therapeutics administered to an individual for a condition involving the enzyme, may be determined.
