SARS-CoV-2/ACE-2 pseudovirus entry blocking assay
The spike glypcoprotein S of SARS-CoV-2 uses the human Angiotensin Converting Enzyme 2 (ACE2) as an entry receptor and recognizes it with a similar affinity to the 2002–2003 SARS-CoV isolates, which suggests it can spread efficiently in humans, in agreement with the numerous SARS-CoV-2 human-to-human transmission events reported to date (Walls et al., 2020).
