How to Read a Peptide Certificate of Analysis
A certificate of analysis is a record of specific tests performed on a specific batch on a specific date. Read line by line, it tells you a great deal — and it stops well short of everything.

Peptide Nomenclature: Sequences, Mass and Identity
The same peptide can appear under a code name, a sequence, a trade designation and a registry number. Knowing how those identifiers relate makes catalog entries checkable.
More articles are in preparation. Nothing is published here until every claim in it can be traced to a document that genuinely exists.
