ACE-2 Antibody [Unconjugated]

Western blot shows lysates of human ovary tissue, human testis tissue, and human kidney tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human ACE‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF933) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for ACE‑2 at approximately 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

ACE‑2 was detected in immersion fixed paraffin-embedded sections of human kidney using Goat Anti-Human ACE‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF933) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

A specific band was detected for ACE‑2 at approximately 155 kDa (as indicated) using 10 µg/mL of Goat Anti-Human ACE‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF933) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background

ACE-2, also called ACEH (ACE homolog), is an integral membrane protein and a zinc metalloprotease of the ACE family that also includes somatic and germinal ACE (1). Human ACE-2 has about 40% amino acid identity to the N- and C-terminal domains of human somatic ACE. The predicted human ACE-2 protein sequence consists of 805 amino acids, including a N-terminal signal peptide, a single catalytic domain, a C-terminal membrane anchor, and a short cytoplasmic tail. ACE-2 cleaves angiotensins I and II as a carboxypeptidase. ACE-2 mRNA is found at high levels in testis, kidney, and heart and at moderate levels in colon, small intestine, and ovary. Classical ACE inhibitors such as captopril and lisinopril do not inhibit ACE-2 activity. Novel peptide inhibitors of ACE-2 do not inhibit ACE activity (2). Genetic data from Drosophila, mice and rats show that ACE-2 is an essential regulator of heart function in vivo (3).

ACE2 has been shown to be a functional receptor of the human coronaviruses SARS-CoV and SARS-CoV-2 (4, 5). This Human anti-ACE2 antibody (catalog # AF933) was used to block the variant SARS-CoV-2 and ACE2 interaction to elucidate viral transmission and potential therapeutic strategies. (5)
