METHOD FOR DETECTING AND QUANTIFYING A TARGET MOLECULE IN A SAMPLE

摘要

The invention relates to a method for identifying and quantifying by mass spectrometry at least one target molecule in a sample,comprising the following steps: a) depositing the sample to be analyzed on a support; b) analyzing the sample by mass spectrometry, so as to obtain the mass spectrum of the target molecule in said sample; c) weighting a signal associated with the mass spectrum of the target molecule in said sample by a extinction coefficient (TEC) specific to the target molecule and to the sample; and optionally d) using the weighted signal of the target molecule to determine the quantity of target molecule in the sample.
