New molecular methods, including competitive polymerase chain reaction (cPCR) and competitive reverse-transcription PCR (cRT-PCR), enable precise absolute quantitation of viral nucleic acids. These techniques are valuable for understanding viral diseases and monitoring antiviral treatments.

Area of Science:

  • Molecular Biology
  • Virology
  • Biotechnology

Background:

  • Significant advancements in molecular methods for nucleic acid quantitation have occurred.
  • Various semi-quantitative and quantitative techniques have been developed and applied in virology research.

Purpose of the Study:

  • To report on the in vivo application of molecular methods for viral nucleic acid quantitation.
  • To demonstrate the utility of these methods in understanding viral disease natural history and monitoring antiviral therapies.

Main Methods:

  • Focus on competitive polymerase chain reaction (cPCR) and competitive reverse-transcription PCR (cRT-PCR) assay systems.
  • Evaluation of theoretical considerations and practical applications of these quantitative molecular methodologies.

Main Results:

  • Successful pilot applications in vivo demonstrate the usefulness of the methods.
  • cPCR and cRT-PCR show advantages over other quantitative molecular techniques for low-amount viral nucleic acid detection.

Conclusions:

  • Competitive PCR-based methods are the preferred choice for absolute quantitation of viral nucleic acids.
  • While minor obstacles for routine clinical virology use exist, further technical evolution is anticipated for broader application.
