Fig. 6From: An Optimized Protocol for Packaging Pseudotyped Integrase Defective LentivirusGene expression levels decrease with incremental cargo size for both wild-type and IDLV. Viral particles were packaged with both wild-type and mutant integrase. The same amounts of viral particles were used for transducing HT1080 cells. Images were taken at Day 3 after transduction. LTR are long terminal repeats derived from HIV provirusBack to article page
