Extended Data Fig. 3: Verification of SARS-CoV and SARS-CoV-2 pseudotypes on 293T cells expressing human ACE2.

A high signal/background ratio of viral entry can be achieved on 293T-hACE2 cells for SARS-CoV and SARS-CoV-2 spike protein pseudotyped VSV-dG viruses expressing Firefly Luciferase (left) and GFP (right).
