What ACE-031 Is
ACE-031 is a soluble ActRIIB-Fc fusion protein that acts as a myostatin/activin pathway inhibitor — a larger biologic rather than a short synthetic peptide. It’s used in preclinical muscle-wasting and muscle-research models because it sequesters the ligands that signal through the activin type IIB receptor.
Because ACE-031 is a recombinant fusion protein, its purity and integrity are assessed differently from short peptides. Correct folding and the absence of aggregates matter as much as sequence confirmation.
Verification for Fusion Proteins
For a recombinant protein like ACE-031, request SDS-PAGE or SEC-HPLC data confirming purity, plus documentation that the material is the expected ActRIIB-Fc construct. A simple peptide HPLC won’t fully characterize a protein.
- Purity (SDS-PAGE / SEC-HPLC): confirms a single dominant band / peak
- Correct construct: ActRIIB extracellular domain fused to Fc
- Low endotoxin: relevant for cell-based assays
- Proper cold-chain handling: proteins are more labile than peptides
FAQ
Is ACE-031 a peptide or a protein?
ACE-031 is a recombinant fusion protein (ActRIIB-Fc), not a short synthetic peptide. It is assessed with protein-specific methods like SDS-PAGE and SEC-HPLC.
How is ACE-031 stored?
Store ACE-031 per the supplier’s cold-chain instructions, typically frozen and protected from freeze-thaw cycles.
Why is ACE-031 used in muscle research?
ACE-031 inhibits the myostatin/activin signaling pathway, making it a tool in preclinical muscle-wasting and muscle-biology studies.
