ACE-031

Description

ACE-031 is a recombinant ActRIIB-Fc fusion protein research material consisting of the extracellular ligand-binding region of activin receptor type IIB joined to an immunoglobulin Fc domain. Unlike short synthetic peptides, ACE-031 is a large, multidomain glycoprotein whose molecular characteristics can be influenced by recombinant expression, glycosylation, disulfide bonding, and protein processing. It is utilized in controlled laboratory environments for analytical, biochemical, ligand-binding, and protein-interaction research under defined experimental conditions.

Research Applications:

ACE-031 may be utilized in controlled laboratory research settings for applications such as:

• Analytical characterization of recombinant fusion-protein identity, molecular size, and structural integrity
• Investigation of ActRIIB-associated ligand-binding interactions in controlled biochemical assay systems
• Evaluation of protein stability, aggregation, and degradation under defined laboratory conditions
• Examination of receptor-ligand and Fc-fusion protein behavior in controlled biochemical and cell-based research models

Storage and Handling:

• Store lyophilized or supplied material according to the manufacturer’s batch-specific storage instructions.
• Many recombinant protein preparations require frozen storage, but confirm the exact temperature in the supplier documentation.
• Protect the material from excessive heat, moisture, and prolonged light exposure.
• Once prepared in solution, follow validated stability and buffer-specific storage conditions for the exact recombinant preparation.
• Avoid unnecessary repeated freeze-thaw cycles and use appropriate protein-handling procedures to minimize aggregation, contamination, and degradation.

Product Specifications:

• Purity: Refer to batch-specific SDS-PAGE, SEC, HPLC, or Certificate of Analysis results
• Appearance: Typically supplied as a lyophilized recombinant protein or formulated solution; confirm against batch-specific documentation
• Expression System: Supplier-specific; verify the recombinant host system used for the actual product
• Oligomeric State: Commonly characterized as an Fc-linked dimeric fusion protein
• Solubility: Dependent on formulation, buffer composition, concentration, pH, and recombinant construct

Compliance Notice:

ACE-031 is FOR RESEARCH USE ONLY. It is not intended for human or veterinary use. This product is supplied exclusively for controlled laboratory, analytical, and in vitro research purposes and is not intended for diagnostic, therapeutic, or clinical applications. Misuse of this product is strictly prohibited and may violate applicable federal, state, or local laws. By purchasing this product, the buyer represents and warrants that it will be used solely for legitimate laboratory research purposes.

Technical Note: ACE-031 should not be listed as a small synthetic peptide with a single fixed molecular formula and molecular weight. It is an ActRIIB-Fc recombinant fusion glycoprotein, and its apparent mass can vary because of glycosylation, Fc dimerization, expression system, construct boundaries, and post-translational processing. Final product-page specifications, including exact amino-acid sequence, molecular weight, glycosylation status, purity, and expression system, should be matched directly to the manufacturer documentation and batch-specific Certificate of Analysis (COA).
