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.
