Key result

Quantitative in situ hybridization achieved +/-10% reproducibility in detecting SV40 replication in monkey kidney cells, but could not detect the integrated genome in transformed cells.

Population

Implication

Quantitative in situ hybridization reliably detects lytic SV40 but misses integrated genomes; leaves open need for sensitive assays in transformation studies.

Outcome
Detection of virus-specific DNA sequences (replication of SV40)

Quantitative in situ hybridization can reproducibly detect SV40 replication in lytic infection but lacks sensitivity for detecting integrated genomes in transformed cells.

Limitations

  • Inability to detect the integrated genome in SV40-transformed cells due to small genome size or low number of genome-equivalents.
  • In SV40-transformed cells, it was not possible to detect significantly the integrated genome due either to the small size of the genome or to the fact that the number of genome-equivalents integrated at the same place is too low to yield a radioactivitity superior to background level for long periods of exposure.

Cite This Study

Langelier et al. (1975) studied SV40 infection. In situ hybridization was evaluated on Detection of viral DNA synthesis. Quantitative in situ hybridization achieved +/-10% reproducibility in detecting SV40 replication in monkey kidney cells, but could not detect the integrated genome in transformed cells.
