Copper-binding tripeptide complex · Updated
A three-amino-acid peptide that forms a complex with copper, which makes its analysis different from that of an ordinary peptide.

Published research areas
Fields in which this compound appears in the published literature. These describe where the research sits, not what it concluded.
- Tissue remodeling models
- The larger part of the published literature, much of it in dermatological research models.
- Copper transport
- Studied as a copper-carrying complex, which is also what distinguishes it analytically from other peptides.
- Gene expression studies
- Investigated in work examining changes in expression profiles in cell culture.
What the analysis should cover
- Copper content, which is not optional here — the complex is defined by the metal, and a peptide-only analysis describes half the material.
- Elemental analysis by ICP-MS therefore carries different weight for this compound than for others, since it quantifies the intended metal as well as screening for unintended ones.
- Identity by mass spectrometry, and purity by HPLC with the trace published.
- Color is a weak but real signal for a copper complex; material should look as the certificate describes.
How to read a certificate of analysis covers what each of these measurements establishes.
Handling and stability
- Supplied freeze-dried and sealed.
- Metal complexes can be sensitive to pH and to chelating agents in ways the free peptide is not.
- Stored cold, dry and dark in the container as supplied.
Why peptides ship freeze-dried sets out the reasoning behind these conditions.
Supplied by us
A copper-binding tripeptide, freeze-dried and sealed in a 100mg vial. Studied in tissue-remodeling and metal-transport research, and used in receptor-ligand and enzyme-substrate work. Every lot ships with its own certificate of analysis.
