METHODS OF QUANTITATION AND IDENTIFICATION OF PEPTIDES AND PROTEINS

摘要

The present invention provides methods of quantifying the amount or concentration of one or more peptides and/or proteins in one or more samples using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to detect differentially isotopically-labeled peptides and/or proteins. The invention also provides methods of identifying one or more peptides and/or proteins in one or more samples.
