To enable the quantification of the protein expression levels in complex biological samples using LC-MS/MS, several different methods have been established. 1). Among the label-free methods two quantification strategies have been established and are widely used for biomarker discovery [10]. 1 Area Under Curve (AUC) or Signal Intensity Measurement This label-free quantification approach is based on measuring the peak areas (area under curve, AUC) for peptide precursor ions, also called peptide ion intensities.

Hence, well-established and robust protocols as well as several commercially available kits for labeling and software packages for data analysis are available for chemical and metabolic labeling. The most prominent metabolic labeling strategy referred to as SILAC (stable isotope labeling by amino acids in cell culture) utilizes a quantification at MS1 level by comparing the signal intensities of peptide ions containing isotopically labeled variants of the amino acids lysine and arginine (one of these amino acids should generally be present in a tryptic peptide) [14].
