(A) Probe-primer sets for real time PCR. The top line with boxes is a genome map around HIV-1 integration site of HIV-1 3’LTR. Numbers with plus and minus under the genome map indicate distances (bp) from the integration site. Arrows and heavy lines are probe-primer sets of real time PCR. (B) Copy numbers of HIV-1 integration site and STAT3 gene. Black, gray and white bars indicate mean copy number per 100 ng DNA of this case, HIV-1-positive Molt4 cell line, and TY-1 (HIV-1-negative, KSHV-positive B cell line), respectively. Copy numbers per 100 ng DNA are indicated on the top of each bar. Error bars indicate standard errors of triplicate samples.
