Cat. No.: HY-P7443
COA Handling Instructions

ACE2 Protein, Human (HEK293, mFc) is a SARS-CoV-2 receptor. Angiotensin-Converting Enzyme 2 efficiently hydrolyses the potent vasoconstrictor angiotensin II to angiotensin. It is a consequence of this action that ACE2 participates in the renin-angiotensin system.

Description

ACE2 Protein, Human (HEK293, mFc) is a SARS-CoV-2 receptor. Angiotensin-Converting Enzyme 2 efficiently hydrolyses the potent vasoconstrictor angiotensin II to angiotensin. It is a consequence of this action that ACE2 participates in the renin-angiotensin system.

Background

Angiotensin-Converting Enzyme 2 (ACE2) is a type I integral membrane protein which functions as a carboxypeptidase, cleaving a single hydrophobic/basic residue from the C-terminus of its substrates. ACE2 efficiently hydrolyses the potent vasoconstrictor angiotensin II to angiotensin. It is a consequence of this action that ACE2 participates in the renin-angiotensin system. However, ACE2 also hydrolyses dynorphin A (1–13), apelin-13 and des-Arg9 bradykinin. The role of ACE2 in these peptide systems has yet to be revealed. A physiological role for ACE2 has been implicated in hypertension, cardiac function, heart function and diabetes, and as a receptor of the severe acute respiratory syndrome coronavirus. This paper reviews the biochemistry of ACE2 and discusses key findings such as the elucidation of crystal structures for ACE2 and testicular ACE and the development of ACE2 inhibitors that have now provided a basis for future research on this enzyme.

Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized Human ACE2, at 2 μg/mL (100 μL/well) can bind Biotinylated SARS-CoV-2 S1 protein. The ED50 for this effect is 8.465 ng/mL, corresponding to a specific activity is 1.18×10^5 Unit/mg.

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.

  • 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
