ACE?031 ? Research Product Description (Compliant, Professional, Non?Medical)
Overview
ACE?031 is a recombinant fusion protein designed for laboratory investigation of myostatin pathway modulation. It combines the extracellular domain of the human activin receptor type IIB (ActRIIB) with a human IgG1?Fc fragment, creating a soluble receptor analog that can bind select ligands within the TGF?? superfamily. This structure makes ACE?031 a valuable tool for studying muscle biology, growth factor signaling, and ligand?receptor interactions in controlled research environments.
Key Research Characteristics
- Type: Recombinant ActRIIB?Fc fusion protein

Research Applications
ACE?031 is commonly used in laboratory settings to explore:
- Ligand binding dynamics within the ActRIIB signaling axis
- Myostatin pathway inhibition models
- Muscle cell differentiation and growth factor signaling
- Receptor?ligand competition assays
