Matrixyl (200mg) Research Peptide: A Matrikine Signalling Peptide for Fibroblast & ECM Studies

If your research investigates fibroblast biology, extracellular matrix (ECM) dynamics, or the molecular mechanisms of collagen synthesis and tissue repair, Matrixyl (200mg) research peptide offers a precisely defined and extensively characterised synthetic tool. Matrixyl (palmitoyl pentapeptide-4, Pal‑KTTKS) is a small, highly specific bioactive lipopeptide consisting of five amino acid residues—lysine, threonine, threonine, lysine, and serine—linked to a palmitoyl (C16 fatty acid) group.

This peptide fragment (KTTKS) is a snippet of type I collagen’s propeptide, and the palmitic acid tail enhances its lipophilicity and ability to interact with lipid bilayers. As a matrikine—a signalling molecule derived from ECM proteins—Matrixyl mimics the natural collagen fragments produced during tissue remodelling, providing feedback to fibroblasts to stimulate the production of new collagen. This makes Matrixyl (200mg) research peptide a valuable tool for laboratories investigating connective tissue biology, wound healing, and the regulation of the extracellular matrix.

At Wuhan Top Miracle Peptides, we supply high‑purity Matrixyl (200mg) 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 ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into fibroblast signalling, collagen synthesis, and ECM remodelling begin with uncompromising quality.

What Is Matrixyl and How Does It Work?

To fully appreciate the research potential of Matrixyl (200mg) research peptide, it is essential to understand its biochemical design and the mechanisms by which it exerts its effects on fibroblasts and the extracellular matrix.

The Pal‑KTTKS Pentapeptide

Matrixyl is a synthetic lipopeptide with the sequence Pal‑Lys‑Thr‑Thr‑Lys‑Ser‑OH (Pal‑KTTKS). Its molecular formula is C₃₉H₇₅N₇O₁₀, and its molecular weight is approximately 802.05 Da. It has a CAS number of 214047‑00‑4.

The peptide consists of a five‑amino‑acid sequence (KTTKS) derived from type I collagen, conjugated to a palmitoyl (C16 fatty acid) chain. The KTTKS sequence is a matrikine—a bioactive fragment that signals fibroblasts to produce new collagen. The palmitoyl group enhances lipophilicity and membrane affinity, allowing the peptide to penetrate lipid bilayers and interact with cellular targets. Matrixyl was launched in 2000 as an active ingredient for the personal care industry under the trade name Matrixyl by Sederma SAS.

Mechanism of Action: Matrikine Signalling and Fibroblast Activation

The biological activity of Matrixyl (200mg) research peptide is mediated through its function as a matrikine that activates fibroblast‑mediated ECM production:

• Matrikine Signalling: Matrixyl functions as a matrikine—a peptide fragment derived from ECM proteins that acts as a signalling molecule to modulate cellular behaviour. By mimicking collagen fragments, it provides feedback modulation of connective tissue remodelling and proliferative cellular processes.

• Fibroblast Activation: The peptide signals fibroblasts to synthesise new ECM components. In 2013, Hamley and colleagues reported that Matrixyl stimulates collagen production in human skin and corneal cells in a concentration‑dependent manner.

• Collagen Synthesis: Matrixyl stimulates the production of elastin, fibronectin, and collagen, especially types I, III, and IV. It promotes ECM support and wound healing.

• Concentration‑Dependent Activity: The collagen‑stimulating effect of C16‑KTTKS has been shown to occur in a concentration‑dependent manner close to the critical aggregation concentration.

Research Note: A Well‑Studied Peptide with Clinical Validation

Matrixyl is one of the most‑studied cosmetic peptides. A double‑blind, randomized trial comparing palmitoyl pentapeptide‑4 (Matrixyl) with acetylhexapeptide‑3 (Argireline) for crow’s feet found that Matrixyl demonstrated better results compared to both Argireline and placebo.

Key Research Applications for Matrixyl (200mg)

Matrixyl (200mg) research peptide is a versatile tool with applications spanning several domains of biomedical research.

1. Fibroblast Biology and ECM Research

• Infected Wound Models: Research has explored Matrixyl derivatives as leads for topical treatment of severely infected skin injuries.

3. Formulation and Delivery System Research

The amphiphilic structure of Matrixyl makes it a useful tool for studying peptide delivery systems:

• Dendrimer‑Based Delivery: Studies have used PAMAM dendrimers functionalised with palmitoyl pentapeptide‑4 for controlled release of active therapeutics into the dermis for 24 hours.

• Solubility Enhancement: Research has investigated how GAO (a solubility enhancer) can improve the sparingly soluble properties of palmitoyl pentapeptide‑4.

• Topical Formulation Studies: Investigating the stability and bioavailability of Matrixyl in various formulation contexts.

4. Comparative Peptide Studies

As a well‑characterised reference compound, Matrixyl serves as a standard for:

• Comparative Efficacy Studies: Comparing Matrixyl with other collagen‑stimulating peptides.

• Structure‑Activity Relationship (SAR) Studies: Investigating how modifications to the KTTKS sequence affect biological activity.

• Mechanistic Studies: Using Matrixyl as a reference to elucidate the mechanisms of other matrikines.

Reconstitution & Handling Protocol for Matrixyl (200mg)

Proper reconstitution of Matrixyl (200mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed Matrixyl vial and your chosen diluent (sterile bacteriostatic water, sterile PBS pH 5‑7, or ethanol) 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 Matrixyl 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 200 mg per 20 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 Matrixyl 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

Adjust diluent volume based on your experimental requirements. For cell culture applications, typical working concentrations range from 0.1‑10 µM.
