Research Peptide Reference Library
This reference hub covers how research peptide lots are verified and handled: purity by reverse-phase HPLC area percent, identity by mass spectrometry, and the certificate of analysis fields that determine how much peptide a vial actually holds.
It also indexes every compound ENOS Labs USA lists, so each compound page, its scientific name and its lot documentation can be reached from one place.
All materials referenced are supplied for in-vitro laboratory research use only. They are not for human or veterinary consumption or administration.
Analytical and handling references
Peptide Purity Testing and How to Read a Certificate of Analysis
A research peptide certificate of analysis (COA) answers two separate questions: identity, established by mass spectrometry, and purity, established by reverse-phase high-performance liquid chromatography (HPLC) reported as area percent of the main peak.
HPLC vs Mass Spectrometry: What Each Test Actually Proves
HPLC separates a sample and reports purity as the area percent of the target peak relative to all detected peaks; it measures composition, not identity.
Reconstitution and Storage Handling for Lyophilized Research Peptides
Lyophilized research peptides are stored dry and cold, reconstituted with a compatible sterile diluent immediately before use, and handled so the solution sees as few freeze-thaw cycles as possible.
Compound index
Every research compound in the catalog, listed by scientific name. Each page carries the compound identity data, the lot certificate of analysis and the relevant analytical references. For deeper background, see the ENOS Lab Notes education library and the research library primers.
