PEG MGF (Pegylated Mechano Growth Factor) 5mg is a premium-grade research peptide supplied by Peptide Hubs with a verified purity of ≥99%. This peptide is a pegylated analogue of Mechano Growth Factor (MGF), an IGF-1 splice variant associated with cellular responses to mechanical stimulation. The addition of a polyethylene glycol (PEG) chain enhances molecular stability and significantly extends the peptide’s functional lifespan in research environments, making it suitable for studies requiring prolonged peptide activity. PEG MGF is widely explored in experimental research focused on cellular growth signaling, muscle biology, and tissue regeneration pathways. Its modified structure allows researchers to observe sustained interactions with IGF-related signaling cascades, offering valuable insight into processes such as cell proliferation, differentiation, and repair mechanisms. Compared to native MGF, the pegylated form demonstrates improved resistance to enzymatic degradation, which is beneficial for time-dependent assays and extended observation models.
