How to read a Certificate of Analysis
Anatomy of a COA: lot identifiers, HPLC purity trace and integration, ESI-MS identity confirmation, water content, residual solvents, and what each release criterion means.
Reference brief · in preparation
Laboratory Reference
Methods, documentation, and material literacy.
Reference material for qualified researchers on how peptide reference compounds are synthesized, characterized, documented, and handled in the laboratory. This page is educational and does not provide protocols, dosing, or any guidance for human or animal use.
Research Use Only — Not for Human or Veterinary Use. Content on this page describes laboratory methodology, analytical chemistry, and documentation practices. It is not medical, clinical, dosing, or therapeutic guidance. Materials sold by Peptides Bioscience are reference compounds for in-vitro laboratory research only.
Reference topics
Short, focused references on laboratory practice and documentation literacy.
Peptide synthesis & purification basics
Solid-phase peptide synthesis (SPPS) overview, Fmoc vs Boc chemistry at a high level, reverse-phase HPLC purification, lyophilization, and why purity figures are reported as area-% by HPLC.
Reference brief · in preparation
Storage & cold-chain handling
Recommended storage of lyophilized peptides, ambient excursion tolerances during transit, and general principles of freeze-thaw stability for in-vitro stock solutions.
Reference brief · in preparation
Reconstitution math for in-vitro stocks
Molecular weight, mass-to-mole conversions, and dilution math for preparing laboratory stock solutions. Worked-example references — not protocols and not dosing guidance.
Reference brief · in preparation
Glossary of peptide families & receptor classes
Plain-language definitions of incretin analogs, melanocortin peptides, GH secretagogues, BPC / TB / GHK peptides, neuropeptides, and NAD+ / pineal peptides — what these compounds are, structurally and pharmacologically in vitro.
Reference brief · in preparation
RUO vs GMP vs USP-grade materials
How material grades differ in documentation, manufacturing controls, and intended use. Why Research Use Only materials are appropriate for in-vitro work and inappropriate for any human or veterinary application.
