Peptide research, explained
Evidence-based articles on peptide chemistry, synthesis, analytical testing, documentation and handling — written for researchers who need to understand what they are buying and how to verify it. Each article links to the relevant product and quality pages.
Foundations
What Are Peptides?
A clear, scientific introduction to peptides: how they are defined, how they differ from proteins, and why synthetic peptides are used in laboratory research.
Read articleMethods
Peptide Synthesis Explained
How research peptides are synthesized: solid-phase peptide synthesis (SPPS), Fmoc and Boc protecting-group strategies, cleavage, and the purification steps that precede analytical characterization.
Read articleAnalytics
Peptide Purity Testing
How peptide purity is measured in the laboratory: reverse-phase HPLC for purity, mass spectrometry for identity, and why orthogonal methods are required for reliable characterization.
