ACE2 Protein, Cynomolgus (HEK293, hFc)

ACE2 Protein, Cynomolgus (HEK293, hFc) is a metallopeptidase which binds effectively to the S1 domain of the SARS‐CoV protein. ACE2 is also an essential regulator of cardiac function and blood pressure control.

Angiotensin‐converting enzyme 2 (ACE2), a metallopeptidase, is the functional receptor for SARS‐CoV. ACE2 can be immunoprecipitated by the S1 domain of the SARS‐CoV virus and that ACE2 can promote viral replication. ACE2 is abundantly present in humans in the epithelia of lung and small intestine, which might provide possible routes of entry for the SARS‐CoV. ACE2, previously identified as the cellular receptor for SARS-CoV, also acts as a receptor of the new coronavirus (SARS-CoV-2). ACE2 is also thought to be an essential regulator of cardiac function and blood pressure control, possibly by acting as a natural counterpart of ACE1^[1][2].

Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 0.2 μg/well can bind Cynomolgus-ACE2, the EC₅₀ is 2.380-10.94 ng/mL.

Approximately 116 kDa

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, 6% trehalose, pH 7.4.

<1 EU/μg, determined by LAL method.

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

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
