The SRMAtlas is a compendium of targeted proteomics assays to detect and quantify proteins in complex proteome digests by mass spectrometry. It results from high-quality measurements of natural and synthetic peptides conducted on a triple quadrupole mass spectrometer, and is intended as a resource for selected/multiple reaction monitoring (SRM/MRM)-based proteomic workflows (See Kusebauch, U. et al., Cell 166: 766, 2016; Doerr A, Nature Meth 13:712, 2016) Registration not required.
