PEG MGF 5mg

PEG MGF 5mg is a highly stable, pegylated analog of endogenous Mechano-Growth Factor (IGF-1Ec), precision-engineered for advanced laboratory research. Available at ≥98% purity, this formulation features covalent polyethylene glycol (PEG) conjugation that dramatically extends biological half-life, enabling precise in vitro and in vivo modeling of tissue repair, myoblast proliferation, and cellular hypertrophy. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

PEG MGF — or Pegylated Mechano-Growth Factor — is a synthetic analog derived from IGF-1Ec, the human splice variant of Insulin-like Growth Factor-1 (IGF-1) that is naturally upregulated in response to mechanical loading or localized tissue trauma. By conjugating the native MGF peptide to a polyethylene glycol moiety, researchers gain access to a significantly stabilized reagent with prolonged circulatory residence time compared to unmodified MGF. The Peptide Store supplies this compound in a premium lyophilized 5mg format, purpose-built for intensive research protocols requiring consistent, reproducible biological activity across extended experimental timelines.

Peptide Structure & Amino Acid Sequence

PEG MGF is structurally derived from the C-terminal E-domain of IGF-1Ec. The biologically active peptide core — often referenced by its 24-amino acid E-peptide sequence — is covalently conjugated to a high-molecular-weight PEG chain. This pegylation is site-specific, preserving the receptor-binding domain’s conformational integrity while providing steric shielding against proteolytic enzymes. The resulting macromolecular construct retains the myogenic signaling properties of native MGF while exhibiting markedly superior aqueous stability and enzymatic resistance, making it an ideal tool for mechanobiology and satellite cell research.

Chemical & Physical Characteristics

• Compound Type: Pegylated synthetic peptide analog (IGF-1Ec E-domain)
• Modification: Covalent PEG conjugation for extended half-life
• Molecular Weight: Variable; PEG conjugate significantly increases native MW
• Appearance: White to off-white lyophilized powder
• Solubility: Soluble in sterile aqueous buffers and standard laboratory solvents
• Storage Stability: Lyophilized form exhibits excellent long-term stability under recommended conditions

Purity & Analytical Verification (HPLC & MS)

Every batch of PEG MGF 5mg supplied by The Peptide Store is independently verified to ≥98% purity using reverse-phase High-Performance Liquid Chromatography (RP-HPLC). Mass Spectrometry (MS) analysis is performed to confirm molecular identity and validate the integrity of the PEG conjugation. Certificates of Analysis (CoA) reflecting these analytical results are available upon request, providing researchers with the documentation necessary for institutional compliance, grant reporting, and peer-reviewed publication support.

Quality Control & Lyophilization Integrity

PEG MGF 5mg is produced under stringent quality control protocols that encompass raw material sourcing, synthesis validation, and post-lyophilization integrity testing. The lyophilization process is optimized to remove residual moisture while preserving the three-dimensional structure of the pegylated peptide construct. Each vial undergoes visual inspection and weight verification prior to dispatch. This rigorous quality assurance framework ensures that researchers receive a consistent, high-integrity reagent suitable for demanding experimental applications.

Safety, Handling & Laboratory Precautions

PEG MGF 5mg is a research-grade reagent intended exclusively for qualified laboratory professionals operating within appropriately equipped research environments. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and a laboratory coat — should be worn at all times when handling this compound. Researchers should consult applicable institutional biosafety guidelines and Safety Data Sheets (SDS) before initiating any experimental protocol. This compound is not evaluated for safety in humans or animals and must not be administered to any living organism outside of formally approved, ethics-reviewed research settings.

Reconstitution, Packaging & Storage

PEG MGF 5mg is supplied as a sterile lyophilized powder in a sealed, laboratory-grade vial. For reconstitution, researchers should refer to peer-reviewed literature and institutional SOPs appropriate to their specific experimental design. Upon receipt, the lyophilized product should be stored at −20°C or below, protected from light and moisture. Reconstituted solutions should be prepared fresh for each experimental session where possible and stored according to validated laboratory protocols. The Peptide Store packages all peptides with protective inert-atmosphere sealing to maximize shelf life and maintain purity integrity during transit.

Intended Research Use & Market Positioning

PEG MGF 5mg is positioned as a premium research tool for investigators working in the fields of musculoskeletal biology, mechanobiology, satellite cell dynamics, tissue remodeling, and myogenic signaling pathways. Its extended half-life profile relative to native MGF makes it particularly well-suited for longitudinal in vitro cell culture studies and controlled in vivo animal model research where sustained peptide availability is required. The Peptide Store offers this compound for sale to academic institutions, pharmaceutical research organizations, and licensed laboratory facilities seeking a reliable, analytically verified source of pegylated MGF.
