The in vitro virus (IVV) assay is often a cell-centered assay used to exam mobile tradition harvest samples for potential viral contaminants39. It will be able to detect a wide range of viruses and was applied as an outstanding Regulate (QC) good deal launch assay in all 15 events that were performed less than cGMP producing.
