  • 产品描述：

    The recombinant human ACE2 is prepared by the expression of a target fragment corresponding to 18-740aa of the human ACE2 protein with a human Fc tag at the C-terminus in the mammalian expression system.
    The monocarboxypeptidase ACE2, a homolog of ACE, is a negative regulator of the renin-angiotensin-aldosterone system (RAAS). It plays a protective role in the cardiovascular system and many organs by balancing multiple functions of ACE. And ACE2 is also the primary target for SARS-CoV-2 and facilitates viral invasion into the host cells. Binding with an amino acid transporter, ACE2 is conducive to the absorption of amino acids in the kidney and intestines.
    This human ACE2 contains endotoxin less than 1.0 EU/ug as determined by the LAL method, and its purity is over 85% as measured by SDS-PAGE. It has high reactivity and binding-affinity with SARS-CoV-2-S1 and SARS-CoV-2-S1-RBD, which were verified in the functional ELISA and LSPR assay, respectively. As is well-known, a recombinant protein tagged with Fc is relatively more stable & productive and efficient to be purified by protein A. And this ACE2 protein carries a hFc-tag, which can bind to the Fc receptor on the surface of immune cells, exerting multiple biological effects.

  • 功能：
    Essential counter-regulatory carboxypeptidase of the renin-angiotensin hormone system that is a critical regulator of blood volume, systemic vascular resistance, and thus cardiovascular homeostasis. Converts angiotensin I to angiotensin 1-9, a nine-amino acid peptide with anti-hypertrophic effects in cardiomyocytes, and angiotensin II to angiotensin 1-7, which then acts as a beneficial vasodilator and anti-proliferation agent, counterbalancing the actions of the vasoconstrictor angiotensin II. Also removes the C-terminal residue from three other vasoactive peptides, neurotensin, kinetensin, and des-Arg bradykinin, but is not active on bradykinin. Also cleaves other biological peptides, such as apelins (apelin-13, Non-functional as a carboxypeptidase.; (Microbial infection) Acts as a receptor for human coronaviruses SARS-CoV and SARS-CoV-2, as well as human coronavirus NL63/HCoV-NL63.; (Microbial infection) Non-functional as a receptor for human coronavirus SARS-CoV-2.
