| Method for determining the concentration of proteins through a combination of protein digestion and liquid chromatography-mass spectrometry (LC-MS) without relying on stable isotope labeling. Protein quantification is achieved by measuring the signal intensity of peptide ions corresponding to a protein or by counting and comparing the number of fragment mass spectra identifying peptides of a given protein. |
