The rcVSV-S virions were preincubated with representative clones of Family A clone 10D6 (FA-10D6), Family B clone FB-1D10 (FB-1D10), Family D clone 2C1 (FD-2C1), Family E clone 14G5 (FE-14G5), and Family G clone 10A3 (FG-10A3) prior to infection of Vero-ACE2-TMPRSS2 cells and analyzed for GFP fluorescence by a Celigo cytometer (Fig. 1). The gene discussed is ACE2; the disease is infection.
