COVID-19 is caused by a novel Coronavirus (CoV) called SARS-CoV-2, also known as 2019-nCoV. The disease outbreak was first discovered in Wuhan, China but has spread to many other countries with up-to-date millions of laboratory-confirmed infections and several hundred thousand of fatal cases. The World Health Organization (WHO) has declared a global health emergency to gather resources and remedy this threat.
Background
There are four coronavirus genera: alpha-coronavirus, beta-coronavirus, gamma-coronavirus, and delta-coronavirus. SARS-CoV-2 belongs to the beta-coronavirus genus originating from bats. Beta-coronaviruses can infect mammals, are zoonotic pathogens, and can cause severe respiratory disease in humans.
Other viruses in this family are SARS coronavirus (SARS-CoV) and MERS coronavirus. SARS-CoV-2 has approximately 79% sequence identity to SARS-CoV and 50% to MERS-CoV which gives us clues as to how it may infect and cause disease in humans. In addition, homology modeling shows SARS-CoV-2 has a similar receptor-binding domain structure as SARS-CoV which suggests SARS-CoV-2 uses the angiotensin-converting enzyme-2 (ACE2) receptor in humans for infection. A significant amount of research has already been done to understand ACE2 and how it may be used as a host receptor by viruses, giving us a head-start when fighting COVID-19.
The ACE2 SARS-CoV-2 Interaction

ACE2 is expressed in the human heart, lung, kidney and gastrointestinal tract and is an essential regulator of heart function and blood pressure. ACE2 is a functional receptor, acting as the entry point into human lung cells for both SARS-CoV and the human respiratory coronavirus (HCoV-NL63). This makes it a potential target for therapy that could prevent COVID-19 infection.
Research into the interaction between SARS-CoV-2 and ACE2 is key as this dynamic is crucial to understanding both cross-species and human to human transmissions of COVID-19.
Tools to Study COVID-19

To support the efforts of researchers worldwide to study, understand and combat this new health threat, PromoCell offers a range of high-quality antibodies specifically directed against components of the SARS-CoV-2 and the ACE2 receptor.
As ACE2 is a potential therapeutic target not only for cardiovascular disorders but also for coronavirus-induced diseases, we also provide an ACE2 Activity Assay as well as an ACE Inhibitor Screening Assay to further support research progress in this field.
