SARS-CoV-2 causes cytopathic effect on cell monolayers. About 70%-80% confluent cells were inoculated with SARS-CoV-2 at MOI of 0.1 plaque forming unit (PFU)/cell and incubated for 1 hour. After incubation, wells were washed with PBS (3X), replaced with fresh growth media, and monitored for cytopathic effect at the indicated timepoints. The last panel images represent negative controls at day 6. Images were collected using an inverted light microscope (10x magnification for all images).
