Sensitivity of PCR screening for XMRV in PBMC DNA. VP62 plasmid was serially diluted 1:10 into PBMC DNA from a healthy donor and tested by Taqman PCR with env 6173 primers and probe. The final amount of VP62 DNA in the reaction was A, 2.3 × 10-2 ng, B, 2.3 × 10-3 ng, C, 2.3 × 10-4 ng, D, 2.3 × 10-5 ng, E, 2.3 × 10-6 ng, F, 2.3 × 10-7 ng or G, 2.3 × 10-8 ng. The limit of sensitivity was 2.3 × 10-7 ng (shown by trace F) which equates to 16 molecules of VP62 XMRV clone.
