The Human Proteome Peptide Catalog

JPT offers the most extensive library of validated human reference peptides for mass-spectrometry based proteomics. The human reference peptide library covers essentially all human proteins and is your fast and low-cost access to light & heavy labelled proteotypic peptides.
In the ProteomicsDB you will find high confidence spectra for each peptide (Zolg et al. Nat. Meth. 2017). 

Peptides are available as
