Active Recombinant Human ACE2, Fc-tagged

• Cat.No.: ACE2-68H
• Product Overview: Recombinant Human ACE2 (aa 1-740) are fused at the C-terminus to the Fc portion of human IgG1.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized from sterile 100mM Glycine, 10mM NaCl, 50mM Tris, pH 7.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2 (2019-nCoV) Spike S1-His at 2 μg/mL (100 μL/well) can bind human ACE2 (hFc tag), the EC50 of ACE2 is 5-35 ng/mL.
• Molecular Mass: The recombinant human ACE2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 961 amino acids and predicts a molecular mass of 110.3 kDa. As a result of glycosylation, the rhACE2/Fc monomer migrates as approximately 145-150 kDa band in SDS-PAGE under reducing conditions.
• Protein Length: Met 1-Ser 740
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % 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.
