Massenspektrometrie bezeichnet ein Verfahren zum Messen der Masse von Atomen oder Molekülen. Die zu untersuchenden Moleküle werden dabei in die Gasphase überführt und ionisiert. Die Ionen werden anschließend durch ein elektrisches Feld beschleunigt und dem Analysator zugeführt, der sie nach ihrem Masse-zu-Ladung-Verhältnis m/z sortiert, beispielsweise räumlich in Teilstrahlen auftrennt wie in einem Sektorfeld-Massenspektrometer. Die Moleküle können dabei fragmentiert werden. Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions.

Untargeted mass spectrometry is employed to detect small molecules in complex biospecimens, generating data that are difficult to interpret. We developed Qemistree, a data exploration strategy based on the hierarchical organization of molecular fingerprints predicted from fragmentation spectra. Qemistree allows mass spectrometry data to be represented in the context of sample metadata and chemical ontologies. By expressing molecular relationships as a tree, we can apply ecological tools that. Methods: We conceived the mass pattern paradigm (MPP) that enables the creation of such an identification method, and we implemented it into a prototype database search engine PRiSM (PRotein‐Spectrum Matching). We then assessed its operational characteristics by applying it to publicly available high‐precision mass spectra of low and high identification difficulty. We used.

The Golm Metabolome Database (GMD) facilitates the search for and dissemination of reference mass spectra from biologically active metabolites quantified using gas chromatography (GC) coupled to mass spectrometry (MS).

Furthermore, precise MHC-I peptide identification from mass spectrometry (MS) data is especially important in designing therapeutic targets that could be used to formulate personalized CD8 + T-cell-based therapies such as vaccines against infectious diseases. Additionally, for vaccine-based cancer immunotherapies, MS-enabled identification of tumor-associated MHC-I ligands or those containing. Mass Spectral libraries and databases provide the opportunity to automatically analyze large amounts of MS n data and identify many small molecule components, as well as transferring knowledge from research into more routine, quantitative applications. However, analysts require certainty for unknown identifications, which means that libraries, databases and knowledge stores must contain high.
