Detection by PCR of human polyomaviruses BK and JC in immunocompromised individuals and partial sequencing of control regions.

abstract：:A real-time PCR assay was developed for quantitative detection of B19 DNA in clinical serum samples. The assay was carried out using a LightCycler instrument and product formation was monitored continuously with the fluorescent double-stranded DNA binding dye SYBR Green I. With an optimized PCR protocol, this system w...
