Product Details
PEG MGF is a PEGylated variant of Mechano Growth Factor, a muscle-specific splice isoform of IGF-1 (IGF-1Ec) that is released in response to mechanical stress. The covalently linked polyethylene glycol significantly prolongs the half-life in research models compared to native MGF.
The PEG MGF lyophilisate is produced under controlled conditions and analyzed for purity and degree of PEGylation.
Research Relevance
- Satellite cell activation — research into the role of the MGF C-terminal fragment in muscle repair.
- Mechano-transduction — models involving mechanical loading and local growth factor signaling.
- Extended half-life — PEGylation makes long-term in vitro studies practically feasible (native MGF has a half-life of minutes).
- Comparison with IGF-1 — investigation of isoform-specific effects within the IGF-1 gene family.
Independently tested by Janoshik Independent Peptide Analytics for purity, heavy metals, and endotoxins.
Frequently Asked Questions
What is PEG MGF?
PEG MGF is a PEGylated version of Mechano Growth Factor—a muscle-specific splice isoform of IGF-1 (IGF-1Ec). The C-terminal 24-amino acid fragment is covalently linked to polyethylene glycol for enhanced stability.
What purity is guaranteed?
Janoshik validates each batch for HPLC purity ≥ 99%, with additional analysis for heavy metals and endotoxins.
How should PEG MGF be stored?
Store the lyophilisate refrigerated (2–8 °C), protected from light and moisture. Do not open vials until immediately before reconstitution.
