PEG MGF (Pegylated Mechano Growth Factor) is a synthetic 24-amino-acid peptide derived from the C-terminal Ec splice variant of insulin-like growth factor 1 (IGF-1Ec), conjugated with polyethylene glycol (PEG) to extend plasma stability in research models. It has been studied in preclinical research models of skeletal muscle satellite cell activation, mechanical-load-induced signaling, and growth factor biology. Heartland Bio Labs supplies PEG MGF as a high-purity lyophilized research compound for qualified laboratory and research use only.
PEG MGF is referenced in published preclinical literature on muscle hypertrophy and tissue repair. In vitro and in vivo studies have investigated its activity in myoblast and satellite cell models, with research interest focused on the IGF-1Ec C-terminal sequence, mechanical-stress signaling pathways, satellite cell quiescence/activation, and downstream growth factor cascades. The PEG conjugation has been studied as a stability-modifying modification relative to native MGF.
This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.
Handling Information
PEG MGF should be handled under standard laboratory conditions. Use appropriate personal protective equipment. Avoid repeated freeze-thaw cycles once reconstituted. Handle with care to minimize degradation of the peptide structure. This compound is intended for use by qualified research professionals only.
