Research Guides
What Are Research Peptides? A Plain-English Guide
Peptides are short chains of amino acids used as reference compounds in the lab. Here's what that means, how they're identified, and why the paperwork matters.
HPLC Purity & COAs: How to Read a Peptide Certificate
Purity and identity are two different questions — and a good Certificate of Analysis answers both. Here's how to actually read one instead of trusting a number.
Peptide Storage & Stability: Keep Research Peptides Intact
Peptides degrade when you're careless with temperature, light, and freeze-thaw cycles. Here's the cold-chain cheat sheet that keeps your material — and your results — honest.
How to Reconstitute Research Peptides: A Step-by-Step Lab Guide
Reconstituting a lyophilized peptide is mostly arithmetic and a steady hand. Here's the concentration math, the exact steps, and the mistakes that ruin a good vial.
