Evaluation of the specificity of the BLV-CoCoMo-qPCR primers. (A) Real-time PCR using the CoCoMo 6 and CoCoMo 81 primers from the BLV-CoCoMo-qPCR was performed using 0.3 ng of the following infectious molecular clones: BLV (pBLV-IF, lane 2); HTLV-1 (pK30, lane 3); HIV-1 (pNL4-3, lane 4); SIV (pSIVmac239/WT, lane 5); MMTV (hybrid MMTV, lane 6); M-MLV (pL-4, lane 7); and the plasmids pUC18 (lane 8), pUC19 (lane 9), pBR322 (lane 10), and pBluescript SK(+) (lane 11). PCR products were subjected to 3% agarose gel electrophoresis. Lane 1, DNA marker Φ × 174-Hae III digest. A PCR product 168 bp in length is indicated by an arrow. (B) The number of BLV provirus copies in 1 μg of DNA from each DNA sample is indicated by lowercase. Values represent the mean ± standard deviation (SD) of the results of three independent experiments.
