PEG-MGF is a PEGylated form of mechano growth factor (MGF), a splice variant of IGF-1 (IGF-1Ec) produced in response to mechanical stress. The PEGylation extends stability in research systems.
Research models study its role in muscle satellite-cell activation and proliferation pathways, distinct from systemic IGF-1 signaling.
Every Ethos Bio lot of PEG-MGF is analyzed by reverse-phase HPLC and independently confirmed by mass spectrometry through our third-party testing partner, Janoshik Analytical. A signed Certificate of Analysis documenting identity and ≥99% purity is provided for every lot.
Independent third-party HPLC & mass-spec verification. The COA shipped with your order reflects your specific lot.
What is PEG-MGF?
PEG-MGF is a PEGylated mechano growth factor, an IGF-1 splice variant (IGF-1Ec), studied for satellite-cell proliferation pathways in research models. It is sold for research use only.
Why is MGF PEGylated?
PEGylation extends the stability and research half-life of mechano growth factor in laboratory systems.
Is PEG-MGF related to IGF-1?
Yes — MGF is a splice variant of IGF-1 (IGF-1Ec) studied for localized satellite-cell effects distinct from systemic IGF-1 signaling.
