title: Enveloped virus labeling via both intrinsic biosynthesis and metabolic incorporation of phospholipids in host cells.
abstract: An alternative method for labeling fully replicative enveloped viruses was developed, in which both the biosynthesis and metabolic incorporation of phospholipids in host cells were simultaneously utilized to introduce an azide group to the envelope of the vaccinia virus by taking advantage of the host-derived lipid membrane formation mechanism. Such an azide group could be subsequently used to fluorescently label the envelope of the virus via a bioorthogonal reaction. Furthermore, simultaneous dual-labeling of the virus through the virus replication was realized skillfully by coupling this envelope labeling strategy with "replication-intercalation labeling" of viral nucleic acid. For the first time, it is by natural propagation of the virus in its host cells in the presence of fluorophores that simultaneous dual-labeling of living viruses can be mildly realized with high efficiency in facile and mild conditions.
