Fig. 3From: The effect of HIV-1 Vif polymorphisms on A3G anti-viral activity in an in vivo mouse model Vif sequences are retained in viruses passaged in vivo. PCR analysis. a DNA isolated from the spleens of the mice infected with the different viruses was PCR-amplified with primers flanking vif (5′-atggaaaacagatggcaggt-3′/5′-ctagtgtccattcattgta-3′). b Sequences of the revertant viruses found in the Y20H-, K22E- and K22H-infected miceBack to article page
