MGF (5MG)

What Is MGF and Why Buy It for Research?

Buy MGF 5mg in Switzerland for research into muscle repair, satellite cell activation, and tissue regeneration mechanisms. Specifically, MGF (also known as Mechano Growth Factor, IGF-1Ec, or MGF E-domain peptide) is a synthetic 24-amino acid linear peptide corresponding to the unique C-terminal E-domain of the human insulin-like growth factor-1 Ec (IGF-1Ec) splice variant. The peptide has the sequence H-Tyr-Gln-Pro-Pro-Ser-Thr-Asn-Lys-Asn-Thr-Lys-Ser-Gln-Arg-Arg-Lys-Gly-Ser-Thr-Phe-Glu-Glu-His-Lys-NH₂ (one-letter code: YQPPSTNKNTKSQRRKGSTFEEHK-NH₂).

Geoffrey Goldspink and colleagues at University College London first identified MGF as a muscle-specific splice variant of the IGF-1 gene that becomes markedly up-regulated in exercised or damaged muscle. Unlike the systemic liver-derived IGF-1, MGF is a local autocrine/paracrine factor expressed as a pulse following muscle damage and is involved in the activation of muscle satellite (stem) cells. The peptide has a molecular weight of approximately 2,848-2,867 Da and the molecular formula C₁₂₁H₂₀₀N₄₂O₃₉. The CAS number for MGF is 80214-83-1.

In scientific research, MGF serves as a molecular tool for studying satellite cell activation, muscle repair, and tissue regeneration pathways. Furthermore, Core Peptides supplies MGF as a lyophilized powder in a 5mg format exclusively for laboratory use. Therefore, researchers seeking to source this compound for their work will find it readily available when they buy MGF 5mg in Switzerland.

MGF Research Overview: Buy MGF 5mg in Switzerland for Satellite Cell Studies

Centrally, research into MGF has focused on its function as a local growth factor that activates quiescent satellite cells and promotes muscle progenitor cell proliferation. MGF is the product of a unique muscle-specific splice variant of the IGF-1 gene. In humans, a 49-base pair insert from exon 5 of the IGF-1 gene causes a reading frame shift in the IGF-1Ec transcript, producing a completely different carboxy-terminal peptide sequence compared to the predominant IGF-1Ea isoform.

Unlike mature IGF-I, the distinct E domain of MGF inhibits terminal differentiation whilst increasing myoblast proliferation. Blocking the IGF-I receptor with a specific antibody indicated that the function of the MGF E domain is mediated via a different receptor. MGF does not bind to IGF-1 binding proteins, which are responsible for stabilization of IGF-1 in blood and in muscle.

Furthermore, a clear nuclear localization signal (NLS) “RRRK” within the Ec peptide has been identified. The peptide is characterized by a high basicity with four lysine residues and two arginine residues, giving it a strong net positive charge at physiological pH. Additionally, the proline-rich N-terminus (positions 3 and 4 are both proline residues) introduces a rigid kink in the peptide backbone that may be important for biological activity. Accordingly, researchers who buy MGF 5mg in Switzerland from Core Peptides can support their investigations into satellite cell activation, muscle repair, and tissue regeneration.

How Does MGF Work in Research?

Mechanistically, MGF’s proposed action involves functioning as a local autocrine/paracrine factor that activates quiescent satellite cells and promotes myoblast proliferation through pathways independent of the classical IGF-1 receptor. The peptide operates through several interconnected mechanisms.

Satellite Cell Activation

MGF is expressed as a pulse following muscle damage and is involved in the activation of muscle satellite (stem) cells. MGF is responsible for activating quiescent satellite cells, which proliferate to provide a pool of myogenic precursor cells for muscle repair. The peptide significantly increases the proliferative life span and delays senescence of satellite cells.

Myoblast Proliferation vs. Differentiation

Unlike mature IGF-I, the distinct E domain of MGF inhibits terminal differentiation whilst increasing myoblast proliferation. MGF increases cellular proliferation and inhibits terminal differentiation of myoblasts necessary for secondary myotube formation. This dual action allows MGF to expand the progenitor cell pool before IGF-1Ea drives differentiation.

Independent Receptor Signaling

Blocking the IGF-I receptor with a specific antibody indicated that the function of the MGF E domain is mediated via a different receptor. This suggests that MGF signals through a distinct pathway from mature IGF-1, contributing to its unique biological effects.

Nuclear Localization Signal

A clear nuclear localization signal (NLS) “RRRK” within the Ec peptide has been identified. This motif may facilitate nuclear translocation of the peptide or its interactions with nuclear targets, potentially contributing to its gene-regulatory effects.

Why Is MGF Studied in Switzerland?

Primarily, researchers study MGF because it represents a well-characterized IGF-1 splice variant peptide that enables investigation of satellite cell activation, muscle repair, and tissue regeneration. In fact, this compound offers a focused tool for studying the molecular mechanisms underlying muscle adaptation, age-related muscle decline, and regenerative biology.

Research has demonstrated MGF’s relevance across multiple domains. MGF has been shown to significantly increase the proliferative life span and delay senescence of satellite cells isolated from neonatal and young adult muscle. The peptide has been investigated for its potential to combat age-related sarcopenia without the oncogenic side effects observed for IGF-1.

Furthermore, MGF has demonstrated neuroprotective effects in brain ischemia and has been studied for its ability to increase progenitor cells in ALS, dystrophic, and normal muscle. The peptide has also shown potential in preserving cardiac function during myocardial infarction. Ultimately, researchers who buy MGF 5mg in Switzerland gain access to a comprehensive research tool for investigating satellite cell activation, muscle repair, neuroprotection, and tissue regeneration.

How to Evaluate MGF Quality for Research

When sourcing MGF peptide for laboratory research, researchers should consider several quality indicators:

• Identity Confirmation: Analytical techniques such as mass spectrometry should confirm the compound’s molecular weight (approximately 2,848-2,867 Da) and sequence (H-Tyr-Gln-Pro-Pro-Ser-Thr-Asn-Lys-Asn-Thr-Lys-Ser-Gln-Arg-Arg-Lys-Gly-Ser-Thr-Phe-Glu-Glu-His-Lys-NH₂).
• Purity Assessment: High-performance liquid chromatography (HPLC) should verify purity, with ≥95% considered standard for research-grade material.
• Batch Traceability: Lot numbers and batch information enable researchers to track specific production runs.
• Certificate of Analysis: A CoA should accompany the product, detailing analytical testing results including HPLC purity and identity confirmation.
• Labeling Accuracy: Proper labeling should clearly indicate the product name, amount (5mg), sequence, molecular formula, CAS number, and storage recommendations.
• Storage Conditions: Appropriate storage at -20°C or below in desiccated, dark conditions helps maintain peptide stability.

Understanding the Certificate of Analysis

Typically, a Certificate of Analysis (CoA) accompanies research peptides and provides information about the specific batch’s analytical testing. For example, a CoA may include product identity confirmation, purity percentage as determined by HPLC, batch or lot number for traceability, analytical methods used (e.g., mass spectrometry, HPLC), and a physical description of the product.

Nevertheless, it is important to note that a CoA does not establish safety, efficacy, therapeutic effectiveness, or suitability for human use. Instead, it serves as a quality control document that helps researchers verify the identity and purity of the peptide they are using in their laboratory investigations.

Storage and Stability of MGF

Core Peptides supplies MGF as a lyophilized (freeze-dried) powder. To maintain stability and integrity:

• Store the lyophilized powder desiccated at -20°C or below for long-term storage
• Store at 4°C for short-term storage if frequent access is required
• Avoid repeated freeze-thaw cycles
• Weigh under dry conditions; the peptide is hygroscopic
• Reconstitute only immediately before use with appropriate sterile solvents (sterile water or bacteriostatic water)
• Inject solvent slowly against the inner wall of the vial; avoid vigorous agitation during dissolution
• Filter sterilize if required (e.g., 0.22 µm) immediately prior to use
• Aliquot and store reconstituted solutions at -20°C or below to minimize degradation
• Protect from light and moisture; prolonged exposure to light, elevated temperature, or aqueous environments may reduce stability
