Research peptide buyer guides
Plain-English guides to buying research peptides — how to choose a vendor, read a Certificate of Analysis, store and handle material, and compare prices. For laboratory research use only.
A practical checklist for choosing a research-peptide vendor — third-party COAs, purity testing, US sourcing, and how to compare prices across suppliers.
What each line on a peptide COA means — lot identity, HPLC purity and its chromatogram, mass-spec identity, water content, and endotoxin — and how to verify it.
General lab guidance for storing and handling research peptides — lyophilized vs reconstituted, temperatures, protecting from light, and avoiding freeze–thaw.
Bacteriostatic water is a common solvent for reconstituting lyophilized research peptides. What it is, how it differs from sterile water, and where to buy it.
Peptides are short chains of amino acids. Here is what that means, how peptides differ from proteins, how they are synthesized, and how the main research-peptide families are grouped.
