The S686G mutation has negative effect on the ability of SARS-CoV-2 virus to form syncytia. Vero/ACE2 cells in 6-well Costar plates were infected with the indicated variants at an MOI of 2 PFU/cell and incubated in serum-free media for 16 h at 37°C. Then they were fixed by 4% PFA, and images were acquired on EVOS microscope. Syncytia are indicated by black arrows.
