Why laboratories choose pens and cartridges
A contained 3ml presentation supports clear product identification, consistent format comparison and documented repeat procurement. Compatible refill cartridges also allow an organisation to retain its reusable pen hardware while ordering the required prepared research presentation separately.
This item is prepared only after ordering to minimise elapsed time in the prepared state before dispatch. Refrigerate at 2-8 C and protect from light on receipt. Stability is compound-, preparation- and storage-dependent, so retain and follow the supplied product and batch documentation.

Description and research context
GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. The peptide provides a defined metal-binding scaffold, allowing biochemical studies to distinguish effects associated with the GHK ligand, copper availability and the assembled complex.
In cultured fibroblast systems, GHK-Cu has been investigated for changes in extracellular-matrix turnover, including MMP-2, TIMP and glycosaminoglycan measurements. Responses vary with copper status, concentration, exposure time and model.
Applications in research
- Copper binding, transport and peptide-metal interaction assays
- MMP, TIMP and extracellular-matrix turnover measurements
- Fibroblast gene-expression and glycosaminoglycan model systems
Precautions and interpretation
For controlled laboratory research only. Not for human or veterinary use. The cited findings come from specific biochemical, cellular, structural or preclinical models and must not be treated as usage guidance or evidence of a defined outcome outside those models.
