Figure 2. PCR strategy for amplifying both the complete HTLV-1c proviral genome (figure 2A) and the entire Long Terminal Repeat (LTR) region (figure 2B).

Both LTR-gag, pro-pol, pol-env and tax-LTR fragments, which were amplified by PCR and sequenced are shown (orange arrows) as well as internal primers pairs (purple arrows) designed for sequencing reactions (see table 2 for oligonucleotide primers sequences). Nucleotide numbering is according to the HTLV-1 ATK-1 prototypic sequence (Genbank: J02029).
