Title
(EN) Detection and Quantification of Polypeptides Using Mass Spectrometry
Abstract
(EN)

The invention relates to the detection and quantification of polypeptides using mass spectrometry. Specifically, the invention provides a method for testing whether a target polypeptide is present in a sample of a set of polypeptides, a method for deriving a value for distinguishing polypeptides of a set of polypeptides from each other, a database containing values for distinguishing each polypeptide of a set of polypeptides from each other, and an apparatus for configuring a mass scan of a mass spectrometer to test whether a target polypeptide of a set of polypeptides is present in a sample of the set.
