ACE-031

ACE-031 Chemical Information:

• Chemical Name: ActRIIB-Fc fusion protein (Activin Receptor Type IIB / IgG1-Fc); also referenced as ACVR2B-Fc
• Molecular Weight: ~80 kDa (homodimeric); ~58 kDa per glycosylated monomer (apparent, SDS-PAGE)
• Structure: Recombinant homodimeric fusion protein; 343-amino-acid monomer with N-glycosylation sites
• Compound Class: Recombinant fusion protein (soluble decoy receptor)

Product Description: ACE-031 is a recombinant fusion protein composed of the extracellular domain of the human activin receptor type IIB (ACVR2B) linked to the Fc region of human immunoglobulin G1 (IgG1). Unlike synthetic peptides, ACE-031 is a large glycosylated protein produced through mammalian cell expression systems rather than solid-phase peptide synthesis. This product is a research-grade reagent and is not manufactured under GMP conditions; it is not equivalent to, or a substitute for, any clinical- or pharmaceutical-grade material. It is supplied as a lyophilized protein intended exclusively for controlled in-vitro laboratory research by qualified professionals studying activin/TGF-β superfamily signaling pathways. This product is not formulated for clinical, diagnostic, or therapeutic use. Research Applications:

• In-vitro investigation of ActRIIB ligand-trap binding interactions within the TGF-β superfamily
• Laboratory studies of myostatin (GDF-8) and activin signaling in cell-based assay systems
• Comparative evaluation of fusion-protein decoy receptors and ligand-sequestration models
• Analytical method development and reference characterization for recombinant fusion proteins

Storage and Handling:

• Store lyophilized protein at -20 °C to -80 °C for long-term stability
• Reconstituted solutions should be stored at 2–8 °C and used promptly; avoid repeated freeze–thaw cycles
• Protect from light and elevated temperatures
• Handle using appropriate laboratory safety and aseptic techniques

Product Specifications:

• Purity: ≥95% (SDS-PAGE / SEC, refer to Certificate of Analysis)
• Appearance: White lyophilized protein
• Solubility: Soluble in suitable laboratory agents
• Form: Lyophilized protein
