ACE2, receptor of SARS-CoV-2

ACE2, receptor of SARS-CoV-2

The novel coronavirus (SARS-CoV-2) which caused an epidemic of acute respiratory syndrome shares 79.5% sequence identify to SARS-CoV. Recently, several reports indicated that SARS-CoV-2 and SARS-CoV share the same receptor ACE2 for mediating viral entry into host cells.

ACE2 (angiotensin-converting enzyme-2) is previously known as the receptor for SARS-CoV. Based on structural analysis, Wan et al., and Xu et al., point that ACE2 could be the receptor for SARS-CoV-2. Zhou et al., conducted virus infectivity studies and confirmed that ACE2 is required for entry of 2019-nCoV into HeLa cells. More understanding about the interaction of SARS-CoV-2 and ACE2 can lead to anti-infective strategies such as ACE2 protein blockade or neutralizing antibodies.

arigo offers IP-grade AEC2 antibody (ARG41099) that is excellent for studying the interaction of SARS-CoV-2 and ACE2 and the vital infection. Moreover, a series of antibodies and ELISA kit are available to facilitate coronavirus research.
