PEG-MGF
Muscle repair & satellite cell activation
PEG-MGF (PEGylated Mechano Growth Factor) is a splice variant of IGF-1 that is upregulated in response to mechanical stress and muscle damage. The PEGylation process extends its half-life significantly, allowing for sustained activation of muscle satellite cells and enhanced repair.
- ✓Activates muscle satellite cells
- ✓Extended half-life via PEGylation
- ✓Promotes muscle repair post-exercise
- ✓Splice variant of IGF-1
- ✓≥99% purity — HPLC verified
Mechanism of Action
PEG-MGF is a PEGylated splice variant of IGF-1 produced in response to mechanical load or tissue damage. PEGylation extends its half-life from minutes to several days. It activates satellite cells (muscle stem cells) and promotes their proliferation and differentiation, making it a key research tool for muscle repair and hypertrophy models.
