Figure 1From: Neutralization sensitivity of HIV-1 subtype B’ clinical isolates from former plasma donors in ChinaNeighbor-joining tree depicting the genetic relationship among the HIV-1 isolates. A number of commonly used reference sequences for classifying HIV-1 subtypes (in bold) and CRFs were included. All the isolates from Anhui (AHxxxV) were close to B.FR.HXB2 (HIV-1 subtype B) and closer to B.CN.RL42 (Thai B’) based on the phylogenetic analysis of gp120 gene.Back to article page
