  Numerous approaches have been used to evaluate HIV-1 drug resistance,replicative fitness,and/or tropism (co-receptor usage).More important,different assays are usually needed to quantify these characteristics in vitro.Here,we have developed and optimized a novel system cell-based assay which allows the simultaneous study of these viral parameters using dual-infections with EGFP/DsRed2-tagged viruses.HIV-1 replicative competent viruses were generated as fluorescent variants expressing EGFP or DsRED proteins in a NL4-3 genotypic background.
