Mass Spectrometry Data center
Biochemical Reference Data for Protein and Proteome Analysis
(Developed by the Mass Spectrometry Data Center at NIST)
Comprehensive, annotated mass spectral libraries from various organisms and selected proteins to identify peptides by matching their MS/MS spectra to reference spectra.
The libraries are provided in two formats - NIST MS Search binary format and ASCII format ( MSP file). You can use MSP files with your software. The NIST MS Search binary libraries is usable with NIST MS Search program.
You can download NIST MS Peptide Search and additional software here:
