| Assay Description: | A CPE-based viral inhibition assay for measuring the antiviral activity of peptides against live HCoV-229E was established as we did for detecting anti-Zika virus activity. Briefly, a 50 µL peptide solution was mixed with 50 µL of HCoV-229E (VR-740, 100 TCID50). After incubation at 37 °C for 1 h, the mixture was added to Huh-7 or A549 cells seeded in 96-well plates, followed by incubation at 37 °C for 12 h [53]. The culture supernatant was replaced with fresh and serum-free DMEM. Three to eight days later, when 229E-induced CPE became evident, antiviral activity was detected using the Cell Counting Kit-8 (CCK8, Dojindo, Kumamoto, Kyushu, Japan), according to the instruction manual. Data were then collected by microplate reader (Tecan). |
