Virological Assays

Virus titration (titer: TCID50/mL)
  • Nasopharyngeal (NP) swabs in VTM; eight 10-fold serial dilutions on Vero-E6 cells. Reporting in TCID50/mL.
  • Read out on 6 day post inoculation based on CPE readout (crystal violet) and confirmation by ViroSpot immunostaining on all positive samples.
Antiviral assays (IC50)
  • Antivirals; IC50 measurement using a serial dilution of eight – eleven concentrations.
  • Wild type SARS-CoV-2, Vero-E6 cells, 96-well plates, ViroSpot immunostaining readout.
