DOI
Digital Object Identifier — a permanent unique identifier for an academic paper or other published artefact.
A Digital Object Identifier (DOI) is a permanent, unique identifier assigned by Crossref (and other registration agencies) to an academic paper, dataset, or other digital artefact. DOIs do not change even if the publisher's URL changes — they resolve via doi.org/{identifier}. For research peptide literature, a DOI is the most permanent way to cite a paper; PMIDs are usually preferred for biomedical work because PubMed indexing is curated.
- GlossaryCOA (Certificate of Analysis)
Document showing the analytical results — typically purity, mass, and identity — for a specific batch of research peptide.
- GlossaryHPLC
High-performance liquid chromatography — the standard purity assay for research peptides.
- GlossaryMass spectrometry
Identifies a compound by measuring its mass-to-charge ratio.
