Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized 2019-nCoV Spike Protein at 2 μg/mL (100 μL/well) can bind Biotinylated ACE2 Protein, Human (sf9, His-Avi) and the EC50 is 20-40 ng/mL.




Sf9 insect cells




Q9BYF1 (M1-S740)

Gene ID
Angiotensin-converting enzyme 2; ACE-2; ACEH; ACE-related carboxypeptidase
AA Sequence


Molecular Weight

Approximately 86.86 kDa


Greater than 95% as determined by reducing SDS-PAGE.


Lyophilized powder.


Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.0, 5% glycerol. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

Endotoxin Level

<1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
