Peptide knowledge for laboratory practice
Everything we know and can show about research peptides: basics, analytics, legal status and the tools we use ourselves. Every page separates what is established from what remains open.
Four foundations
1. What are peptides?
Amino acid building blocks, the peptide bond, the difference from proteins and why length and order determine properties.
2. What research uses peptides for
The questions laboratories answer with peptides, from receptor signalling to tissue models, and where the line to human use runs.
3. Quality and analytics
What HPLC, mass spectrometry and content measurement show, how a lab report is built and how to verify it at the laboratory.
4. Legal status and responsibility
Why the intended use decides, what medicines and anti-doping rules mean, and the rules we sell by.
