| Assay Description: | MERS-CoV S protein-mediated cell–cell fusion was assessed, as described previously.(PMID: 25331705, 25451066) In brief, 293T cells expressing MERS-CoV S protein and enhanced GFP (EGFP) were used as the effector cells (293T/MERS/EGFP), and Huh-7 cells expressing the MERS-CoV receptor DPP4 were used as the target cells. 293T/EGFP cells, which express only EGFP, were used as negative control cells. Huh-7 cells were plated in a 96-well plate (5 × 10^4 per well) and cultured at 37 °C for 5 h. Inhibitors at the indicated concentrations were then added, followed by the addition of 293T/MERS/EGFP cells or 293T/EGFP cells (1 × 10^4 per well). After coculture at 37 °C for 4 h, the 293T/MERS/EGFP cells and 293T/EGFP cells fused or unfused with Huh-7 cells were counted under an inverted fluorescence microscope (Nikon Eclipse Ti–S). |
