Active Recombinant Human ACVR2A protein, hFc-tagged

• Cat.No.: ACVR2A-195H
• Product Overview: Recombinant Human ACVR2A protein(NP_001607.1)(Met1-Pro134), fused with hFc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: Met1-Pro134
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation.The ED50 for this effect is typically 20-80 ng/mL in the presence of 10 ng/mL recombinant Activin A.
• Molecular Mass: The recombinant human ACVR2A/Fc chimera is a disulfide-linked homodimer protein generated after removal of the signal peptide. The monomer comprises 352 amino acids and predicts a molecular mass of 40.0 kDa. As a result of glycosylation, the monomer migrates as an approximately 60-65 kDa protein in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.

Sotatercept and other ACVR2A-Fc fusion proteins used for cross-reactivity testing were either custom synthesized (Sotatercept; Creative BioMart) or bought from Creative BioMart and R&D Systems (see Table 2).
