From: Viral complementation allows HIV-1 replication without integration
Phenotypic complementation between WT and D116N in virions. Target cells from virus transfer experiment in Figure 4. Two days after infection of target cells bright and dim GFP+ cells were sorted by FACS, then qPCR for integrated DNA was performed on the sorted cells. The integration of D116N-GFP DNA demonstrates that integrase mutant genomes are complemented by WT integrase within virions.
