What is ACE-031?
ACE-031 (ACVR2B-Fc) is a soluble activin receptor type IIB-Fc fusion protein that functions as a ligand trap for myostatin (GDF-8), activin A, GDF-11, and other TGF-β superfamily members. By sequestering these negative regulators of muscle mass, ACE-031 provides a powerful research tool for studying muscle growth signalling, neuromuscular biology, and metabolic regulation. For published research, see PubMed studies on ACE-031{:target=“_blank” rel=“noopener”}.
ACE-031 was originally developed as a therapeutic candidate for Duchenne muscular dystrophy and has since become an important reagent in muscle biology and TGF-β pathway research.
Best-Peptides supplies research-grade ACE-031 with guaranteed ≥95% purity and full analytical documentation.
How Does ACE-031 Work?
Ligand Trap Mechanism
- Myostatin sequestration - High-affinity GDF-8 binding
- Activin A neutralisation - Broad TGF-β ligand capture
- GDF-11 trapping - Additional anti-ageing ligand
- Decoy receptor - Prevents membrane receptor engagement
Downstream Signalling Blockade
- Smad2/3 inhibition - Blocks phosphorylation cascade
- Transcriptional derepression - Removes growth-limiting signals
- mTOR pathway release - Enables protein synthesis
- MyoD/myogenin activation - Promotes myogenic programme
Fc Domain Properties
- Extended half-life - IgG1-Fc confers stability
- Bivalent binding - Dimeric structure enhances avidity
- Protein A purification - Facilitates research-grade production
- Effector function - Engineered for research applications

FAQ
ACE-031 is a soluble form of activin receptor type IIB fused to an IgG1-Fc domain (ACVR2B-Fc). It functions as a ligand trap, sequestering myostatin, activin A, GDF-11, and other TGF-β superfamily members to study their roles in muscle growth, metabolism, and tissue homeostasis.
ACE-031 acts as a decoy receptor, binding circulating myostatin and activins with high affinity before they can engage membrane-bound ActRIIB. This prevents Smad2/3 phosphorylation and downstream transcriptional programmes that normally limit muscle growth.
Both are myostatin inhibitors but work differently. ACE-031 is an engineered receptor-Fc fusion protein with broad TGF-β ligand trapping, while follistatin is a natural binding protein with different ligand selectivity and pharmacokinetic properties.
Store lyophilised ACE-031 at -20°C for long-term stability. Once reconstituted, keep at 2-8°C and use within 2 weeks. Avoid repeated freeze-thaw cycles as this may affect protein conformation.
Our ACE-031 is ≥95% pure as verified by SDS-PAGE and SEC-HPLC. Each batch includes a Certificate of Analysis with purity data, endotoxin testing, and bioactivity confirmation.
Yes, ACE-031 is frequently studied alongside follistatin, GDF-8 propeptide, and anti-myostatin antibodies to compare mechanisms, potency, and ligand selectivity across different inhibition strategies.
Reconstitute in sterile PBS or bacteriostatic water. Add solvent slowly and gently swirl—do not vortex, as this may denature the fusion protein. Aliquot to avoid freeze-thaw cycles.
ACE-031 is available in 1 mg vials, supplied in packs of 10 × 1 mg for research applications.
