Detection of picornavirus genomic and template RNA strands by a novel semi-nested polymerase chain reaction-technique and agarose-gel electrophoresis.
Attempts to evaluate the relative levels of enteroviral genomic and template RNA strands in small biopsy tissue samples from patients have yielded ambiguous data, largely due to the limited amount of RNA available. A novel semi-nested polymerase chain reaction (PCR) technique was developed to enable RNA levels to be examined more accurately. PCR products were visualised by horizontal agarose gel electrophoresis. This technique was demonstrated on linear single-stranded plasmid DNA; viral RNA isolated from a human rhabdomyosarcoma (RD) cell line persistently infected with a mutated coxsackie B5 virus (piRD) and two cell lines, RD and HEp2 cells, acutely infected with a wild-type clinical isolate of coxsackie B5 virus.
