    摘要: Systems and methods are used to store an electronic record of all product ion spectra of all detectable compounds of a sample. A plurality of product ion scans are performed on a tandem mass spectrometer one or more times in a single sample analysis across a mass range using a plurality of mass selection windows. All sample product ion spectra of all detectable compounds for each mass selection window are produced. All sample product ion spectra for each mass selection window are received from the tandem mass spectrometer using a processor. All sample product ion spectra for each mass selection window are stored as an electronic record of all detectable compounds of the sample using the processor. The electronic record is used to characterize compounds known at the time the electronic record is stored or to characterize compounds that became known after the electronic record was stored.

    摘要: The invention relates to a method for the determination of an MRM or SRM assay for a protein of interest, a peptide of interest, or a group of proteins/peptides of interest or a whole proteome. It essentially includes the following steps: (1) a list of proteins of interest is selected and for each member at least one or a list of candidate proteotypic peptides is derived (2) this at least one peptide is synthesized/generated essentially without subsequent purification; (3) this at least one unpurified peptide is analyzed by selected reaction monitoring (SRM) preferably coupled to liquid chromatography (LC-SRM) or analogous techniques; (4) validation and/or optimisation of the corresponding assay of the at least one peptide with determination of the SRM coordinates for a peptide/protein of interest and/or of a regulator of interest is achieved. A protein sample of interest is enzymatically digested and can then be analyzed in SRM mode or time-constrained SRM mode, using elution times to trigger acquisition of the set of selected SRM traces, thus drastically increasing the throughput. The analysis allows to detect and quantify the set of peptides/proteins of interest. The method additionally relates to a tagging strategy to achieve absolute quantification of the peptides/proteins of interest at low-budget and high-throughput.
