Product Info

Product Name Angiotensin converting enzyme 2 (ACE2), Rabbit Polyclonal Antibody
Product Description google SARS-CoV Spike Antibody: A novel coronavirus has been identified as the causative agent of SARS (Severe Acute Respiratory Syndrome). Coronaviruses are a major cause of upper respiratory diseases in humans. The genomes of these viruses are positive-stranded RNA approximately 27-31kb in length. SARS infection can be mediated by the binding of the viral spike protein, a glycosylated 139 kDa protein and the major surface antigen of the virus, to the angiotensin-converting enzyme 2 (ACE2) on target cells. This binding can be blocked by a soluble form of ACE2.
Alternative Names ACE2 Antibody: ACEH, Angiotensin-converting enzyme 2, ACE-related carboxypeptidase, ACEH, SARS-CoV receptor, SARS-CoV-2 receptor
Application(s) ELISA, ICC, IHC-Paraffin-embedded, WB
Antibody Host Rabbit
Antibody Type Polyclonal
Specificity Anti-ACE2 has no cross response to ACE1. Predicted species reactivity based on immunogen sequence: Bovine: (93%)

Scientific Background
ACE2 Antibody: Angiotensin-converting enzyme 2 (ACE2) plays a central role in vascular, renal, and myocardial physiology. In contrast to its homolog ACE, ACE2 expression is restricted to heart, kidney, and testis. Recently. ACE2 has also been shown to be a functional receptor of the SARS coronavirus. Homology modeling shows 2019-nCoV has a similar receptor-binding domain structure as SARS-CoV, which suggests COVID-19 (2019-nCoV) may use ACE2 as a receptor in humans for infection. The normal function of ACE2 is to convert the inactive vasoconstrictor angiotensin I (AngI) to Ang1-9 and the active form AngII to Ang1-7, unlike ACE, which converts AngI to AngII. While the role of these vasoactive peptides is not well understood, lack of ACE2 expression in ace2-/ace2- mice leads to severely reduced cardiac contractility, indicating its importance in regulating heart function.

Immunohistochemical analysis of paraffin-embedded human kidney tissue using anti-ACE2 antibody (R-1951-100) at 2 μg/mL. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4 °C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.
