Result: 293TT cells expressing hACE2 were pretreated with RBD protein one hour prior to WT, 19del, or 19del + D614G PsV infection.

Figure: Representative bioluminescence and kinetics of mouse infection with 19del or 19del + D614G pseudoviruses (c).
Discussion: It is important to note that WT RBD protein and 19del + D614G PsVs were used in this experiment, suggesting that WT RBD protein administration could have efficacy in preventing infection by some mutant SARS-CoV-2 PsV.
