Lipopeptide (200mg) Research Peptide: An Elastin-Derived Lipopeptide for Fibroblast & ECM Studies

If your research investigates fibroblast signalling, extracellular matrix (ECM) remodelling, or the molecular mechanisms of skin structure and elasticity, Lipopeptide (200mg) research peptide offers a precisely defined synthetic tool. This research‑grade cosmetic peptide corresponds to Biopeptide EL (palmitoyl hexapeptide‑12) — an elastin‑derived lipopeptide designed for topical formulation and in vitro studies. Its sequence, Pal‑VGVAPG (Val‑Gly‑Val‑Ala‑Pro‑Gly), mimics a fragment of the natural elastin protein.

By acting as a chemotactic elastin fragment, it may attract and stimulate fibroblasts involved in dermal repair and regeneration. The addition of a palmitoyl (lipid) chain enhances penetration and biocompatibility with the skin’s lipid barrier compared with water‑soluble peptides, making Lipopeptide (200mg) research peptide a valuable tool for laboratories investigating connective tissue biology, ECM dynamics, and skin ageing research.

At Chinese Grey Peptides, we supply high‑purity Lipopeptide (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 Lipopeptide (Biopeptide EL) and How Does It Work?

To fully appreciate the research potential of Lipopeptide (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 Palmitoylated Hexapeptide

Lipopeptide (Biopeptide EL) is a synthetic lipopeptide with the sequence Pal‑Val‑Gly‑Val‑Ala‑Pro‑Gly (Pal‑VGVAPG). Its molecular formula is C₃₈H₆₈N₆O₈, with an approximate molecular weight of 736.98 g/mol. Synonyms frequently used in research and cosmetic literature include Biopeptide EL and Palmitoyl Hexapeptide‑12.

The peptide consists of a six‑amino‑acid sequence (VGVAPG) derived from elastin, conjugated to a palmitoyl (C16 fatty acid) chain. The VGVAPG sequence is a matrikine—a bioactive fragment that signals fibroblasts to produce new ECM components. The palmitoyl group enhances lipophilicity and membrane affinity, allowing the peptide to penetrate lipid bilayers and interact with cellular targets.

Mechanism of Action: Matrikine Signalling and Fibroblast Activation

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

• Chemotactic Elastin Fragment: The VGVAPG motif acts as a chemotactic elastin fragment that may attract and stimulate fibroblasts involved in dermal repair and regeneration.

• Elastin Receptor Complex Activation: Palmitoyl Hexapeptide‑12 functions through the elastin receptor complex (ERC), a heterotrimeric receptor present on fibroblasts, keratinocytes, and smooth muscle cells.

• Collagen and Hyaluronic Acid Stimulation: Scientific studies suggest that lipopeptides like Biopeptide EL can enhance the production of collagen and hyaluronic acid in skin, improve firmness and elasticity, and act as a potent anti‑ageing active by interacting with cell membranes and fibroblasts to support extracellular matrix renewal.

• ECM Support: The peptide supports increased collagen synthesis in the skin’s extracellular matrix, helping improve firmness and wrinkle appearance. It also promotes hyaluronic acid production, contributing to improved hydration, elasticity and plumpness of the skin.

• Fibroblast Proliferation and Migration: It exhibits chemotactic properties, attracting fibroblasts to sites of damage and stimulating their proliferation. It significantly stimulated human skin fibroblast proliferation, mediated through key signalling pathways such as TGF‑β and MAPK.

Research Note: A Well‑Studied Peptide with Clinical Validation

Palmitoyl hexapeptide‑12 is a well‑studied cosmetic peptide that has been shown to permeate both stratum corneum and epidermal layers. In a clinical study, 4% Biopeptide EL™ (containing Pal‑VGVAPG) applied twice daily for one month improved skin firmness by 33% and skin tone by up to 20% compared to placebo.

Chemical & Physical Specifications for Lipopeptide (200mg)

Accurate characterisation of Lipopeptide (200mg) research peptide is essential for reproducible experimental design.

Note: The 200 mg mass refers to the weight of the peptide in its lyophilised form. Lipopeptide is typically supplied as a TFA or acetate salt, which enhances aqueous solubility. The commercial cosmetic ingredient form is typically listed with INCI: Glyceryl Polymethacrylate (and) PEG‑8 (and) Palmitoyl Hexapeptide‑12.

Reconstitution & Handling Protocol for Lipopeptide (200mg)

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

Step 1 – Preparation

• Bring the sealed Lipopeptide 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 Lipopeptide 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 Lipopeptide 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 for Lipopeptide (200mg)
