Notes
Reference notes on peptide chemistry, specifications and batch documentation. Written for people who work with these reagents.
What research peptides are, and what “high purity” means on a label
How peptides are defined chemically, what separates a research reagent from a medicine, and how purity and identity specifications are written.
How to read a peptide batch test report
What HPLC purity, mass spectrometry identity and Karl Fischer water content report on a certificate of analysis, and how to check a laboratory verification key.
Storing lyophilised peptides: temperature, light and moisture
Why peptides are supplied freeze-dried, what the storage line on a specification table means, and the conditions the specification is written against.
“Research use only”: what the label means and what it does not
The regulatory meaning of a research-use-only reagent label, why these materials are not medicines, and the attestations required before an order is accepted.
What is in a peptide blend: GLOW, KLOW and two-component kits
The exact composition of the blended kits in the catalog — which peptides are present, at what stated amounts, and what the specification covers.
Bacteriostatic water and the other consumables in the catalog
What bacteriostatic water is chemically, how it differs from unpreserved sterile water, and how the consumables in the catalog are specified and stored.
A glossary of the peptide families in this catalog
The nine families the catalog is grouped into, what the products in each have in common chemically, and where each sits in the catalog.
