Snippet: Though it is difficult to assess the virus-host-cell interactions with real virion, we studied the new SARS-CoV-2 in head-to-head comparisons with SARS-CoV using multiple methods. Measurements of recombinant SARS-CoV-2 and SARS-CoV spike proteins to recombinant ACE2 protein and ACE2 expressing 293T cells confirmed the two coronaviruses' similar binding affinities to human ACE2 (Figure 2A&B) , which provided direct molecular based evidences to sup.....
Document: Though it is difficult to assess the virus-host-cell interactions with real virion, we studied the new SARS-CoV-2 in head-to-head comparisons with SARS-CoV using multiple methods. Measurements of recombinant SARS-CoV-2 and SARS-CoV spike proteins to recombinant ACE2 protein and ACE2 expressing 293T cells confirmed the two coronaviruses' similar binding affinities to human ACE2 (Figure 2A&B) , which provided direct molecular based evidences to support and possibly explain the observation that the new SARS-CoV-2 coronavirus has similar transmissibility to SARS-CoV virus.
