Palmitoyl Tetrapeptide-7 (200mg) Research Peptide: An Immunoglobulin-Derived Tool for Inflammation & ECM Studies

If your research investigates the intersection of immunology and extracellular matrix (ECM) biology, Palmitoyl Tetrapeptide-7 (200mg) research peptide — also known as Rigin — is a compound worth serious consideration. This synthetic tetrapeptide (Pal‑Gly‑Gln‑Pro‑Arg) is not derived from connective tissue proteins like many matrikines. Instead, it is a fragment of the human immunoglobulin G molecule, specifically mimicking a bioactive sequence found in the immune system. Its palmitoyl (C16 fatty acid) chain enhances its lipophilicity and membrane affinity, allowing it to interact with cellular targets more effectively. The primary interest in this peptide lies in its unique dual‑action mechanism: it downregulates the production of interleukin‑6 (IL‑6) , a key pro‑inflammatory cytokine, while also stimulating the synthesis of collagen and other ECM components.

At Wuhan Top Miracle Peptides, we supply high‑purity Palmitoyl Tetrapeptide-7 (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 inflammation, ECM biology, and tissue repair begin with uncompromising quality.

What Is Palmitoyl Tetrapeptide-7 and How Does It Work?

To fully appreciate the research potential of Palmitoyl Tetrapeptide-7 (200mg) research peptide, it is essential to understand its unique biochemical origin and the precise mechanisms by which it modulates cellular behaviour.

The Pal‑GQPR Tetrapeptide

Palmitoyl Tetrapeptide-7 is a synthetic tetrapeptide consisting of glycine, glutamine, proline, and arginine (GQPR), conjugated at the N‑terminus with a palmitoyl (hexadecanoyl) group. The sequence is Pal‑Gly‑Gln‑Pro‑Arg‑OH (Pal‑GQPR). Its molecular formula is C₃₄H₆₂N₈O₇, and its molecular weight is approximately 694.9 g/mol It has a CAS number of 221227-05-0.

The compound is also referred to as Rigin and Palmitoyl Tetrapeptide-3. Its unique origin as a fragment of immunoglobulin G distinguishes it from other matrikine peptides, which are typically derived from ECM proteins like collagen. The palmitoyl group—a 16‑carbon saturated fatty acid chain—enhances lipophilicity and membrane affinity, improving the peptide’s ability to interact with cellular membranes and penetrate tissues.

Mechanism of Action: Anti‑Inflammatory and ECM‑Promoting

The biological activity of Palmitoyl Tetrapeptide-7 (200mg) research peptide is rooted in its dual mechanism of action, targeting both inflammatory signalling and ECM synthesis.

• IL‑6 Downregulation: The primary mechanism of Palmitoyl Tetrapeptide-7 is the downregulation of the pro‑inflammatory cytokine Interleukin‑6 (IL‑6) . Elevated levels of IL‑6 are associated with chronic inflammation, a key driver of ECM degradation and tissue ageing. By reducing IL‑6 production, the peptide helps to create a less inflammatory environment.

• Indirect Inhibition of MMPs: Chronic inflammation promotes the upregulation of matrix metalloproteinases (MMPs) —enzymes that degrade essential ECM components like collagen and elastin. By suppressing IL‑6, Palmitoyl Tetrapeptide-7 indirectly inhibits MMP activity, helping to preserve the structural integrity of the ECM.

• Stimulation of ECM Synthesis: Beyond its anti‑inflammatory effects, the peptide is believed to stimulate the synthesis of new collagen and fibronectin, crucial components of the ECM. It acts as a cellular messenger, promoting the regeneration of collagen fibres in the dermis.

• Hyaluronic Acid Production: Palmitoyl Tetrapeptide-7 is thought to increase the amount of hyaluronic acid in tissues, helping to attract moisture and support tissue structure.

Research Potency

In vitro studies have quantified the peptide’s efficacy. For example, in human dermal fibroblasts, Palmitoyl Tetrapeptide-7 has been shown to reduce IL‑6 secretion by up to 40% in a dose‑dependent manner. This robust, quantifiable activity makes it a valuable reference standard for studies investigating inflammatory modulation and ECM preservation.

Reconstitution & Handling Protocol for Palmitoyl Tetrapeptide-7 (200mg)

Proper reconstitution of Palmitoyl Tetrapeptide-7 (200mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed Palmitoyl Tetrapeptide-7 vial and your chosen diluent (sterile PBS, pH 5‑7, or cell culture media) 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 Palmitoyl Tetrapeptide-7 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 Palmitoyl Tetrapeptide-7 into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles.

• Once thawed, store at 2‑8°C and use within one week for short‑term experiments.

Concentration Reference Table

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