GHK Basic (50mg) Research Peptide: An Endogenous Matrikine for Fibroblast, ECM & Collagen Studies

If your research investigates the biology of the extracellular matrix (ECM), fibroblast dynamics, or the molecular mechanisms of tissue repair and regeneration, GHK Basic (50mg) research peptide offers a naturally occurring and extensively studied synthetic tool. GHK (glycyl‑L‑histidyl‑L‑lysine) is a tripeptide first isolated from human plasma in 1973. It is an endogenous matrikine—a signalling molecule released during ECM proteolysis of the SPARC protein. Functioning as a high‑affinity copper(II) chelator with an apparent dissociation constant of approximately 10⁻¹² M at pH 7.4, GHK forms the bioactive GHK‑Cu complex that has been the subject of decades of research.

However, the unbound “basic” form of GHK has begun to emerge as a distinct research focus, with investigators increasingly curious about how this molecule might support processes related to structural maintenance, cellular coordination, and metabolic homeostasis independently of its copper‑bound state. This makes GHK Basic (50mg) research peptide a valuable tool for laboratories investigating fibroblast signalling, collagen synthesis, ECM remodelling, and the molecular biology of tissue repair.

At Wuhan Top Miracle Peptides, we supply high‑purity GHK Basic (50mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥99% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into fibroblast biology, ECM dynamics, and tissue regeneration begin with uncompromising quality.

What Is GHK Basic and How Does It Work?

To fully appreciate the research potential of GHK Basic (50mg) research peptide, it is essential to understand its biochemical identity, its role as an endogenous matrikine, and the mechanisms by which it exerts its pleiotropic effects.

The Endogenous Tripeptide

GHK Basic is a naturally occurring tripeptide with the amino acid sequence Gly‑His‑Lys (GHK). Its molecular formula is C₁₄H₂₄N₆O₄, and its molecular weight is approximately 340.38‑340.4 g/mol. It has a CAS number of 70253‑66‑6.

The peptide was first isolated from human plasma in 1973 and has since been the subject of extensive research into its role in tissue repair, wound healing, and cellular communication. Its plasma concentration is approximately 200 ng/mL, declining with age, which underpins its relevance to age‑related research.

Mechanism of Action: Matrikine Signalling and Cellular Communication

The biological activity of GHK Basic (50mg) research peptide is mediated through several intersecting mechanisms:

• Matrikine Signalling: GHK functions as an endogenous matrikine—a peptide fragment derived from ECM proteins that acts as a signalling molecule to modulate cellular behaviour. It is released during ECM proteolysis of the SPARC protein and provides feedback regulation of connective tissue remodelling.

• High‑Affinity Copper Chelation: GHK possesses a high‑affinity binding site for divalent copper ions, forming the well‑known complex GHK‑Cu. This copper‑binding property is central to many of its biological activities. However, the basic unbound form may still participate in regulatory environments supporting transcriptional behaviour.

• Fibroblast Activation and ECM Synthesis: GHK stimulates both the synthesis and breakdown of collagen and glycosaminoglycans and modulates the activity of both metalloproteinases and their inhibitors. It stimulates collagen, dermatan sulphate, chondroitin sulphate, and the small proteoglycan decorin.

• Gene Expression Modulation: GHK peptides have been documented to modulate gene expression, with the peptide potentially interacting with DNA‑binding proteins or signalling molecules to subtly shift the transcriptional landscape.

• Anti‑Inflammatory and Antioxidant Effects: GHK possesses antioxidant and anti‑inflammatory effects. Research indicates it can eliminate reactive oxygen species (ROS), inhibit inflammation, and prevent cell apoptosis.

Key Research Applications for GHK Basic (50mg)

GHK Basic (50mg) research peptide is a versatile tool with applications spanning several domains of biomedical research.

1. Fibroblast Biology and ECM Research

As a matrikine that signals fibroblasts to synthesise ECM components, GHK Basic is a valuable tool for studying fibroblast function and ECM dynamics. Research applications include:

• Collagen Synthesis Studies: GHK stimulates the production of collagen types I and III in dermal fibroblasts. At concentrations as low as 10⁻¹² M, GHK‑Cu²⁺ stimulates collagen synthesis, reaching a maximum at 10⁻⁹ M with an increase in collagen synthesis of approximately 80%.

• Glycosaminoglycan Production: GHK stimulates the synthesis of dermatan sulphate, chondroitin sulphate, and the small proteoglycan decorin.

• Fibroblast Proliferation: GHK promotes human skin fibroblast proliferation. In related palmitoylated forms, concentrations of 0.01, 0.1, and 1 µM increased the proliferation rate of human dermal fibroblasts by approximately 20%, 45%, and 60%, respectively.

• ECM Remodelling: GHK modulates the activity of both metalloproteinases and their inhibitors, regulating skin protein breakdown and potentially preventing damaged protein accumulation.

2. Wound Healing and Tissue Repair Research

GHK has been extensively studied for its wound‑healing properties. Research has demonstrated:

• Enhanced Wound Closure: In diabetic murine models, collagen dressing loaded with GHK achieved 99.39% wound closure on day 21 compared to 69.49% for plain films.

• Diabetic Ulcers: GHK may speed up wound closure in larger ulcers and reduce the risk of wound infections. One study reported a median of 89.2% wound closure with GHK treatment.

• Increased Glutathione and Ascorbic Acid: GHK‑treated wounds showed enhanced epithelialisation and increased collagen synthesis, fibroblasts, and mast cell activation.

• Angiogenesis: GHK‑Cu increases vascular endothelial growth factor (VEGF) production, potentially leading to new blood vessel formation.

3. Fibrosis Research

GHK has demonstrated potential in modulating fibrotic pathways:

• Pulmonary Fibrosis: GHK reverses age‑related fibrosis by modulating myofibroblast function, activating stemness markers like p63 and PCNA.

• Myofibroblast Apoptosis: GHK induces apoptosis in myofibroblasts, helping to resolve persistent fibrosis.

• Age‑Related Fibrosis: In aging, GHK’s effect on pulmonary fibroblasts may restore youthful phenotypes, improving fibroblast migration and collagen contraction.

4. Antioxidant and Anti‑Inflammatory Research

GHK’s antioxidant and anti‑inflammatory properties make it a valuable tool for studying oxidative stress and inflammation:

• ROS Elimination: GHK demonstrates the ability to eliminate reactive oxygen species and prevent cell apoptosis.

• Inflammation Regulation: GHK may exert anti‑inflammatory effects through the JAK1‑STAT3 pathway.

• Alveolar Macrophage Protection: GHK‑Cu attenuates alveolar macrophage oxidative stress.

5. Gene Expression and Epigenetic Research

GHK’s ability to modulate gene expression positions it as a valuable tool for studying transcriptional regulation:

• Collagen and Elastin Upregulation: GHK may contribute to the upregulation of genes associated with structural proteins such as collagen and elastin.

• ECM Organisation: GHK may influence genes involved in extracellular matrix organisation.

Chemical & Physical Specifications

Accurate characterisation of GHK Basic (50mg) research peptide is essential for reproducible experimental design.

Note: The 50 mg mass refers to the weight of the peptide in its lyophilised form. GHK Basic is typically supplied as a TFA or acetate salt, which enhances aqueous solubility. The peptide is distinct from its copper‑bound form (GHK‑Cu) and from palmitoylated derivatives such as Pal‑GHK.

Reconstitution & Handling Protocol for GHK Basic (50mg)

Proper reconstitution of GHK Basic (50mg) research peptide is critical for maintaining its structural integrity and biological activity. GHK is susceptible to rapid degradation by proteolytic enzymes, so careful handling is essential.

Step 1 – Preparation

• Bring the sealed GHK Basic vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the GHK Basic vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 50 mg per 5 mL of diluent, yielding a 10 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted GHK Basic into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.

• Once thawed, store at 2‑8°C and use within a short period.

Concentration Reference Table
