Viral Growth Assays. Comparison of growth kinetics between control clonal NL4-3 (WT), Q577 mutant viruses (R, N and K), and resistant polyclonal viral pools (W1 and W2). Viral titers were determined by qRT-PCR and compared to a standard curve of known HIV-1 titers (based on p24 antigen levels). Each culture was inoculated with virus containing 1Â ng p24 (average of biological duplicate assays shown with s.d. error bars)
