When searching untargeted tandem mass spectrometry (MS/MS) metabolomics data using spectral libraries, on average only ~5% of the data can be annotated (~10% for human datasets) 1. Unannotated spectra ...

Spectroscopists are often required to identify an unknown compound from a measured spectrum, verifying sample integrity, and defining detected impurities in a sample. Performing a spectral search can ...

Although proteomics is extensively used in immune research, there is currently no publicly accessible spectral assay library for the comprehensive proteome of immune cells. This study generated ...
