Figure 1. Subcloning strategy of the vector containing the HIV-1 subtype C-Δgprt backbone.

Figure 1

Fragment I (A) and Fragment II (B) were digested using BstEII and EcoRI and religated resulting in an HIV-1 subtype C clone lacking a part of GAG, protease and reverse Transcriptase and most of ENV (Fragment I-II (C)). Fragment I-II was linearized using PacI and AccIII to insert the Env region from Fragment III (D) resulting in a final clone, pGEM-HIV-1-C-Δgprt-BstEII-V, that can be linearized using BstEII/EcoRV, ready for In-Fusion cloning with the 1.7 kb GPRT amplicon. • pGEM-HIV-1-C-Δgprt-BstEII-V+GPRT (wild type sequence).
