Sensitivity of oligonucleotide primer-probe combinations used in RT-PCR analysis.
RT-PCR was performed on RNA extracted from mixtures of EBV− CA46 cells and serial 10-fold dilutions (10−2 to 10−6) of the virus-productive B95.8 cells. In the case of EBNA1, Rael cells were used instead of B95.8 cells. RNA was extracted from a total of 20 × 106 cells, and a fraction corresponding to 2 × 106 cells was used for each RT-PCR followed by Southern hybridization.
