PubMed
The US National Library of Medicine's database of biomedical literature citations.
PubMed is a free search engine maintained by the US National Center for Biotechnology Information (NCBI) at the National Library of Medicine. It indexes ~36 million citations from biomedical literature including MEDLINE, life-science journals, and online books. Each indexed paper has a unique PubMed Identifier (PMID). When research literature cites a specific paper, the PMID is the canonical reference — and a PMID link is the highest-quality citation form for AI engines, search engines, and human review.

- GlossaryHPLC
High-performance liquid chromatography — the standard purity assay for research peptides.
