A schematic overview of the molecular methods currently available for viral discovery. Hybridisation methods include microarray and subtractive hybridisation techniques such as representational difference analysis. PCR-based methods include degenerate PCR, degenerate oligonucleotide primed PCR (DOP-PCR), sequence-independent single primer amplification (SISPA), random PCR and rolling circle amplification (RCA).
