What form does ACE-031 ship in and how is it prepared for research use?

ACE-031 is supplied as a lyophilized powder in a sealed vial for laboratory research use only. For research handling it is typically reconstituted with bacteriostatic water, added gently down the vial wall to preserve the fusion protein, and swirled rather than shaken.

How should ACE-031 be stored?

Store the lyophilized vial at -20C, where it remains stable for up to 24 months. Once reconstituted, keep it refrigerated at 2-8C, use within 30 days, protect from light, and minimize freeze-thaw cycles.

Is ACE-031 a peptide or a protein?

ACE-031 is a recombinant fusion protein consisting of the extracellular domain of activin receptor type IIB fused to a human IgG1 Fc region, rather than a small defined-sequence peptide. It is offered strictly for in-vitro and laboratory research applications.

ACE-031 is a recombinant fusion protein (a soluble activin receptor type IIB extracellular domain joined to a human IgG1 Fc region) that has been the subject of research into myostatin (GDF-8) signaling, activin type II receptor pathways, and TGF-beta superfamily ligand binding. Published studies have investigated its role in skeletal muscle mass models, decoy-receptor ligand-trapping assays, and neuromuscular preclinical research settings. It is one of the more frequently referenced myostatin-pathway fusion proteins in muscle-biology and receptor-signaling research literature.
