Peptides 101: a research-context primer

What peptides are, why purity matters, and how to read a certificate of analysis before you order anything.
Peptides are short chains of amino acids — typically fewer than 50 residues — that act as signalling molecules in nearly every biological system. In a research context, they're powerful tools precisely because they're targeted: each sequence binds a specific receptor or enzyme.
Why purity matters
A 95%-pure peptide isn't usable for sensitive in-vitro work. The 5% impurity could be truncated sequences, oxidized analogs, or residual TFA — any of which can confound a binding assay or alter dose-response curves. We publish HPLC and mass-spec data with each batch so you can verify exactly what you're working with.
Reading a CoA
Every certificate of analysis answers four questions:
