Briefly, total RNAs were extracted from the viral culture propagated with the inocula of tissue samples using Trizol reagents (Gibico).
All samples were viral isolates, propagated either in embryonated chicken eggs or in MDCK cell cultures.
Influenza virus samples were all viral isolates propagated either in embryonated chicken eggs or in MDCK cell cultures.
The proposed mechanism involves downregulation of VP16 viral protein entry into the nucleus that prevents expression of early viral genes required to propagate viral infection [ 4, 11, 26, 30, 31].
It tends to increase in the mid-steps because at that point the viral effects are propagating at full speed, and those interactions are usually common to most viral proteins.
VTT and MVTT-S viral stocks were propagated in Vero cells and then purified by centrifugation through a 36% sucrose cushion.
Mutants with the avian PB2-mammalian PB1 pair (AMAA and AMMM) were found to have a 2 log-unit reduction of viral titre when propagated at 37°C (Fig. 4B).
Viral strains were propagated and titrated by plaque assay on Vero cells, as previously described [ 23].
Moreover, BV propagates viral replication and vaginal shedding of the HIV and HSV-2 [ 11, 12].
Single viral clones were propagated in 293 cells and purified by BD Adeno-X Virus Purification Kits (Biosciencesces, Palo Alto, CA, USA).
