Batch bioreactor production of NDV-GFP (A) and NDV-FLS (B) in the 1 L scale. Offline measurements have been taken by frequent sampling. Infectious viral titers have been quantified by TCID50 and total/genomic viral titers were quantified by ddPCR. The time of infection is indicated by a black dashed line within the figure.Vaccines 2021, 9, x13 ofFigure 5. Batch bioreactor production of NDV-GFP (A) and NDV-FLS (B) in the 1 L scale.

Discussion NDV can be a promising viral vector for vaccine improvement which has been studied for its NDV is usually a promising viral vector for vaccine improvement which has been studied for potential application against many human illnesses, and it is nevertheless usually produced its prospective application against quite a few huma.
