ACE2 & Other Related Target Reagents

To support the efforts of researchers worldwide in understanding and combating the COVID-19 virus (SARS-COV-2) and other coronaviruses, ProSci Incorporated provides validated coronavirus receptor ACE2 antibodies, as well as related targets. Check out our ACE2 Antibody (Cat. No. 3217) that was cited in Cell.

What is the ACE2 receptor?

Angiotensin-converting enzyme 2 (ACE2) is an essential regulator of heart function expressed in the heart, lung, kidney, and gastrointestinal tract. In addition, ACE2 is a functional receptor that acts as an entry point into human lung cells for coronaviruses such as SARS and novel coronavirus SARS-CoV-2. Research in SARS-COV-2 and ACE2 interaction is a topic of interest since it plays a key role in both cross-species and human-to-human transmissions of SARS-CoV-2.[i].

SARS-CoV Antibodies

ACE2 receptors interact with the spike protein (S) of SARS-COV-2 as confirmed by structural analysis of SARS-COV-2. The SARS-COV-2  spike protein receptor-binding domain structure is similar to the SARS spike protein[ii] suggesting a similar function. In a study on SARS-CoV, the virus infection occurred in well-differentiated ciliated epithelial cells expressing ACE2 thus the virus enters hosts through the mucosa of the respiratory and gastrointestinal tract.[iii]
