Viral replication of non-VOC and VOCs on Caco-2. Cells were infected at an MOI of 0.0001 for 96 h and culture supernatant was collected at the indicated time points to quantify a RNA copy numbers by RT-qPCR and b viral titers by TCID50 endpoint assay. c Lack of clear CPE is exemplarily shown for Delta at selected time points.
