Description

PEG-MGF (Pegylated Mechano Growth Factor)

Research-Grade IGF-1 Isoform
Tagline: Muscle Repair & Regeneration Research


Product Description

PEG-MGF (Pegylated Mechano Growth Factor) is a pegylated form of MGF, an isoform of insulin-like growth factor-1 (IGF-1) expressed in response to mechanical stress and muscle damage. Pegylation extends the peptide’s half-life, allowing sustained activity in research applications.

Researchers use PEG-MGF in studies exploring muscle hypertrophy, satellite cell activation, tissue repair, and regenerative medicine. It is an important tool in investigating muscle adaptation to mechanical load and injury.

For Laboratory and Scientific Research Use Only. Not for Human Consumption.


Why Researchers Choose PEG-MGF
  • Extended Half-Life: Pegylation significantly prolongs in vivo stability compared to native MGF.

  • Muscle Growth Research: Stimulates satellite cell activation and myoblast proliferation.

  • Regenerative Medicine Relevance: Studied for potential roles in tissue repair and recovery.

  • Synergy with IGF-1: Complements systemic IGF-1 studies by focusing on localized muscle response.

  • Batch Verified: ≥98% purity, HPLC and MS-tested for reproducibility.


Research Data & Handling Tips
  • Reconstitution: Reconstitute with sterile water or bacteriostatic water; swirl gently until dissolved.

  • Solubility: Soluble in water and compatible buffers.

  • Storage: Store lyophilized peptide at -20 °C. After reconstitution, aliquot and store at -80 °C.

  • Stability: Stable for 24 months (lyophilized); use within 4–8 weeks after reconstitution.


Important Note

For laboratory and scientific research only. Not for human consumption, therapeutic, or diagnostic use.

Research

Research Applications

Muscle Hypertrophy & Regeneration

PEG-MGF has been shown to activate muscle satellite cells and promote myoblast proliferation in response to mechanical overload [1].

Tissue Repair Studies

Used in models of muscle injury to investigate accelerated repair and reduced fibrosis [2].

Aging & Sarcopenia Research

Explored as a potential therapeutic model for age-related muscle loss and regenerative decline [3].

Combination Studies with IGF-1

Studied alongside systemic IGF-1 analogues to understand local vs systemic effects of growth factor signaling [4].

Mechanism of Action

Mechanism of Action (How PEG-MGF Works)
  • Satellite Cell Activation: Binds IGF-1 receptors, stimulating quiescent satellite cells to enter the cell cycle [Goldspink 2005].

  • Myoblast Proliferation: Promotes differentiation and fusion of myoblasts into existing muscle fibers [Hill 2003].

  • Pegylation Advantage: Prolongs half-life, maintaining bioactivity for extended periods in vivo [Owino 2001].

  • Local Tissue Repair: Encourages ECM remodeling and reduces scar tissue formation [Hill 2003].

  • Synergistic Growth Response: Enhances anabolic signaling when combined with IGF-1 [McKay 2008].
