Figure 7From: Phenotype and envelope gene diversity of nef-deleted HIV-1 isolated from long-term survivors infected from a single sourceEnv V1V2 and V3 amino acid sequences. HIV-1 Env amino acid sequences spanning the V1V2 (A) or V3 (B) regions of Env genes cloned into pGEM-T-easy were obtained as described in the Methods. Amino acid alignments are compared to Env from HIV-1 NL4-3. Dots indicate residues identical to NL4-3, and dashes indicate gaps.Back to article page
