MGF: Research Profile, Dosages & Supplier Prices
MGF is a growth factor research compound with a molecular weight of 2888.2 g/mol and a research half-life of minutes to a few hours (very short). Mechano Growth Factor (MGF) is a 24-25 amino acid peptide derived from the unique E-domain of IGF-1Ec, a splice variant of the IGF-1 gene expressed in response to mechanical overload and tissue damage. First characterized in stretched muscle fibers, MGF became a foundational tool compound for studying how tissues translate mechanical signals into repair responses.

What is MGF?
Unlike mature IGF-1, the MGF E-domain peptide does not act through the IGF-1 receptor. Research suggests it activates muscle satellite cells and delays their differentiation, expanding the pool of repair-competent cells. Its native half-life of only minutes makes the unmodified peptide suitable mainly for in-vitro and short-window animal work; the PEGylated form (PEG-MGF) is used where sustained exposure is needed.
Mechanism of Action (Research Context)
Acts via an IGF-1R-independent pathway attributed to the IGF-1Ec E-domain: promotes satellite cell activation and proliferation while suppressing terminal differentiation. Distinct from the PI3K/Akt signaling of mature IGF-1.
Research Areas
MGF Dosages in Research
Native MGF degrades within minutes in plasma; most in-vivo research uses the PEGylated form. In-vitro work typically uses nanomolar concentrations. Research-context only.

Storage & Handling
Lyophilized: -20C desiccated. Reconstituted: 2-8C, use within days rather than weeks; this peptide is notably less stable than average once in solution.
