GHK-Cu

GHK-Cu in Laboratory Research

GHK-Cu is copper tripeptide-1 — the tripeptide glycyl-histidyl-lysine bound to a copper(II) ion. The complex occurs naturally in human plasma and gives the lyophilized powder its characteristic blue colour. Its high-affinity copper binding makes it a defined, reproducible copper source for laboratory study, and it is offered in 50 mg and 100 mg vials.

In controlled laboratory environments, investigators use GHK-Cu both as a signalling molecule of interest in its own right and as a precise way to deliver copper under experimental conditions.

Research Applications & Study Focus

Research interest centres on extracellular-matrix biology: collagen and glycosaminoglycan synthesis, antioxidant-enzyme expression, and the regulation of genes associated with matrix turnover. In trace-metal signalling experiments it also serves as a defined copper source, allowing investigators to control copper delivery precisely across conditions.

Consistent lot-to-lot specification lets research groups compare matrix-biology results across studies and time points without unexpected variability.

Purity, Handling & Verification

Each batch is supplied as a sealed, lyophilized vial and is independently analysed by a third-party laboratory using HPLC and mass spectrometry; the full certificate of analysis is published against its lot number, so results can be verified before use. The blue tint of the powder is expected and is not a quality indicator. Store the lyophilized material cool, dry and out of direct light, and reconstitute with bacteriostatic water under standard aseptic laboratory practice.
