Download contaminant FASTA files from putative sources.

Contaminant Databases (automatic download via API)

The contaminants function downloads protein contaminant databases commonly used in proteomics quality control:

• Frankenfield 2022 (default): Universal contaminant library (381 proteins) from Frankenfield et al. – details

• GPM cRAP: Global Proteome Machine common Repository of Adventitious Proteins (116 proteins) – details

Contaminant Databases (manual download guide, not in API)

• CCP cRAP: Cambridge Centre for Proteomics cRAP (125 proteins, requires camprotR R package) – details

• MaxQuant: Contaminant database from MaxQuant (246 proteins) – details
