| Assay: | Cell-cell fusion |
| Assay Description: | The inhibitory activity of a test peptide on HCoV S-mediated cell-cell fusion was determined. Briefly, effector cells (293 T/S/GFP) and target cells (Huh-7 cells) were cocultured in the presence or absence of a test peptide at the indicated concentrations for fusion. After counting the fused and unfused cells, the percentage of cell-cell fusion was calculated, as described above. The percent inhibition of cell-cell fusion was calculated using the following formula as described : [1 − (E − N)/(P − N)] × 100%. “E” represents the percentage of cell-cell fusion in the experimental group. “P” represents the percentage of cell-cell fusion in the positive control group, where 293 T/HCoV S/EGFP cells were used as effector cells, to which only PBS was added. “N” is the percentage of cell-cell fusion in negative control group, where 293 T/EGFP cells were used as effector cells. The IC50 was calculated using the CalcuSyn software provided by T. C. Chou. Samples were tested in triplicate, and all those experiments were repeated twice. |
