Methods & Guides

Guide

How to Read a Certificate of Analysis (COA)

What each line of a peptide COA actually certifies (mass spec identity, HPLC purity, net peptide content, endotoxin and sterility), and how to match a document to the vial in front of you.

Guide

Bacteriostatic Water vs Sterile Water

Why 0.9% benzyl alcohol changes how a reconstituted vial can be handled, and when a single-use diluent is the correct choice. Chemistry and storage only.

Guide

Peptide Storage & Stability Guide

Temperature, light, moisture and freeze-thaw cycles are what degrade a peptide. How each pathway works, and what changes once a vial is reconstituted.

Guide

How HPLC and Mass Spectrometry Verify Peptide Purity

Reverse-phase HPLC measures how much of the material is the peptide; high-resolution MS confirms it is the right molecule. Why both appear on a credible third-party COA.
