Research material · GHK-Cu

GHK-Cu research reference

GHK-Cu is the copper(II)-coordinated form of the tripeptide glycyl-L-histidyl-L-lysine, studied in biochemical and molecular research on peptide-metal coordination, copper-binding chemistry and peptide structure-function relationships. Peptique supplies it as a lyophilized research material with a lot-matched Certificate of Analysis.

01Compound profile

GHK-Cu research material

GHK-Cu is a copper-peptide complex formed when the tripeptide GHK, sequence glycine-histidine-lysine, coordinates a copper ion. The defined three-residue sequence together with its coordinated metal gives laboratories a distinct molecular system for work on peptide chemistry, metal binding, complex formation and analytical characterization.

Researchers should distinguish between the underlying GHK peptide and its copper-coordinated form when keeping analytical records and interpreting results. Peptique supplies the copper complex, GHK-Cu, strictly as a laboratory research material. The scientific information on this page describes compound identity and areas of published investigation only.

02Identification

Research material identification

Accurate compound identification and lot-level documentation are the two components a controlled study depends on. The identifiers below locate the public record for the reference substance; the lot report characterizes the material in the vial.

Compound
GHK-Cu (copper peptide GHK-Cu)
CAS
89030-95-5
Peptide
GHK, glycyl-L-histidyl-L-lysine (CAS 49557-75-7)
Material class
Peptide-copper complex, research material
Form
Lyophilized solid, blue to blue-violet
Intended use
In vitro laboratory research
03Composition

Glycine, histidine, lysine and copper

G, glycine

The first residue of the defined GHK sequence.

H, histidine

The central residue, whose imidazole side chain contributes the functional group relevant to metal coordination.

K, lysine

The third residue, completing the tripeptide and its molecular identity.

Cu, copper

Coordination with copper(II) produces the complex referred to as GHK-Cu and adds the metal-interaction variable to peptide research.

04Research context

Where GHK-Cu appears in the literature

Copper-binding chemistry

Controlled analytical systems examining coordination between the GHK peptide and copper under defined conditions.

Peptide-metal interactions

A defined molecular model for interactions between a peptide ligand and a coordinated metal ion.

Molecular signaling research

Experimental models investigating measurable signaling variables associated with the complex.

Structure-function research

Comparisons of GHK, GHK-Cu and related materials to examine how metal coordination changes measurable characteristics.

05Research environment

Laboratory research applications

Supplied for use within appropriate research environments by personnel familiar with laboratory procedures, material identification, contamination control and experimental documentation.

Material preparation

Suited to laboratory workflows that call for a defined, documented research material inside an established experimental protocol.

Analytical workflows

Suited to controlled procedures where the researcher independently determines material suitability for the assay in hand.

Research documentation

Product identity and lot information support organized laboratory recordkeeping and later review.

Controlled handling

Researchers remain responsible for selecting handling procedures and contamination-control practices.

06Quality documentation

Lot-specific analytical information

Research conclusions should rest on the analytical documentation for the specific production lot being evaluated. General product-page information is not a substitute. The lot report records:

  • Compound identification
  • Production lot reference
  • Declared material quantity
  • Analytical testing information
  • Purity information where applicable
  • Testing methodology where documented
  • Certificate of Analysis for the lot
  • Research material traceability
07Traceability

Research records and lot control

01Identify

Confirm the compound, the selected strength and the lot identifier on the label.

02Match

Open the lot's report in the COA library and confirm the lot number matches.

03Review

Read the laboratory, the sample identifiers, the methods and the reported measurements.

04Preserve

Keep the product, lot, analytical, receipt and storage records with your research documentation.

08Laboratory handling

Storage and container integrity

  • Keep the original sealed container during storage
  • Protect from direct sunlight and excessive heat
  • Store lyophilized material at -20C, protected from light and moisture
  • Inspect container and closure integrity before laboratory use
  • Observe appearance and record it with the lot in your research records
  • Use appropriate contamination-control procedures

10Research FAQ

GHK-Cu research questions

What is GHK-Cu?
GHK-Cu is a synthetic research peptide supplied by Peptique as a lyophilized laboratory material. It is sold for in vitro research and analytical use only.
What form is the material supplied in?
A lyophilized solid in a sealed glass vial. Appearance can vary by lot and does not indicate identity or purity; the lot's Certificate of Analysis does.
Is GHK-Cu intended for human use?
No. Peptique supplies this product strictly for laboratory research. It is not a drug, food, supplement or cosmetic and is not for human or veterinary use.
Does Peptique provide dosing or administration instructions?
No. Peptique does not provide dosing, administration, injection, therapeutic or personal-use instructions for any product.
Why is the lot number important?
Analytical results apply to the tested lot only. The lot on your vial is what links the material in hand to its report in the COA library.
Is analytical documentation available?
Yes. A lot-matched Certificate of Analysis is published for every released lot and is linked from this page and from the COA library.
What does GHK stand for?
The one-letter codes of its three residues: glycine (G), histidine (H) and lysine (K).
What is the difference between GHK and GHK-Cu?
GHK is the tripeptide itself. GHK-Cu is the same peptide in copper-coordinated form. Peptique supplies GHK-Cu. Keep the distinction in your records when documenting compound identity and results.
Why is the solid blue?
Copper(II) coordination gives the complex its characteristic blue to blue-violet colour. Colour is not an identity or purity test; the lot report is.
Is GHK-Cu supplied for cosmetic or topical use?
No. Peptique supplies it strictly as a laboratory research material, not as a cosmetic, skin-care ingredient or topical preparation.
