Understanding PCR Technology: The Basics and Beyond - legacy
PCR technology is expensive and inaccessible
RT-PCR (Reverse Transcription Polymerase Chain Reaction) is a variation of PCR that amplifies RNA rather than DNA. RT-PCR is commonly used to detect viral RNA, such as in COVID-19 testing.
- DNA extraction: The sample is processed to isolate the genetic material.
- Sample collection: A patient provides a biological sample, such as saliva, blood, or nasal swabs.
- Researchers: Exploring the potential of PCR technology in various fields, from gene expression analysis to environmental monitoring.
- Food safety: Detecting genetically modified organisms or disease-causing bacteria in food.
- Target amplification: PCR enzymes amplify the target DNA sequence, creating millions of copies.
- Healthcare professionals: Staying up-to-date with the latest diagnostic tools and techniques.
- Detection: The amplified DNA is then detected using various methods, such as fluorescence or colorimetry.
- Environmental monitoring: Analyzing DNA from environmental samples to monitor pollution and climate change.
