Vero E6 cells acquired from the American Type Culture Collection (ATCC–CRL 1587) were maintained in MEM with stable L-glutamine (PAN-Biotech, Aidenbach, Germany) supplemented with 10% FBS (PAN-Biotech, Aidenbach, Germany), penicillin (100 IU/mL), streptomycin (100 μg/mL) and non-essential amino acids (PAN-Biotech, Aidenbach, Germany). For virus isolation, Vero E6 cells were seeded at 300 000 cells per well in a 6-well cell culture plate and left to adhere overnight. The following day, nasopharyngeal swabs were filtered through a 0.22 μm filter and diluted 1:1 with the addition of MEM with stable L-glutamine supplemented with penicillin (200 IU/mL) and streptomycin (200 μg/mL). Further dilutions to final 1:10, 1:40, and 1:100 were prepared in MEM with stable L-glutamine supplemented with 2% FBS (PAN-Biotech, Aidenbach, Germany), penicillin (100 IU/mL), streptomycin (100 μg/mL) and non-essential amino acids. After 1 h long incubation in a 5% CO2 environment at 37 °C, the inoculum was removed and DMEM with 4.5 g/L glucose and stable L-glutamine (PAN-Biotech, Aidenbach, Germany), supplemented with 2% FBS, penicillin (100 IU/mL) and streptomycin (100 μg/mL), in a volume of 2 mL was added. Cell culture was checked daily for cytopathic effect until day 5 post-infection when the supernatant was collected from the positive cultures.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
