The NISTmAb Mass Spectral Library of Disulfide-Linked Peptides
As a result of a major upgrade of the earlier version of the spectral library, this 2021 New Release added 596 “best” individual spectra (Selected) of disulfide-bonded peptides, in addition to consensus spectra. The details can be found in the library new release note and Readme PDF files.
The library is presented in two parts, including 321 and 907 spectra generated by Orbitrap Fusion Lumos (Lumos) and Q Exactive Hybrid Quadrupole-Orbitrap (QE) mass spectrometers, respectively. Altogether, there are 155 different peptides identified from native SS linkages in the NISTmAb and 207 different peptides detected from experiment-induced SS bonds.
