Welcome to MaCPepDB - Mass Centric Peptide Database

From here you have two options to search the database:

1. Start by searching for a protein by its Accession. From here you can search the peptides contained in the protein.
2. Start by searching for peptides. There are several possibilities. Search directly for a sequence or a weight, digest a sequence or a protein and use the weight of one of the resulting peptides. You also have the possibility to refine the search with various filters.

Both options are available in the menu.
