Construction and characterization of chimeric BHIV (BIV/HIV-1) viruses carrying the bovine immunodeficiency virus gag gene

Figure 6 Relative reverse transcriptase activities of chimeric virions in 1 mL supernatant of 293T cells (mean±SD, n = 4). All samples are positive to negative control (^bP<0.01 vs negative control). The RT activity of pCG1 virion was lower than the other three chimeric virions and HIV positive control (^dP<0.01 vs pCG1).
