(utilisation du rt pcr)
A: RT-PCR is primarily used to detect and quantify RNA, enabling the diagnosis of RNA-based viruses like SARS-CoV-2. It converts RNA into complementary DNA for amplification, making it essential for sensitive pathogen detection. Laboratories rely on it for high-accuracy diagnostics.
A: Unlike standard PCR, which amplifies DNA, RT-PCR first reverse-transcribes RNA into DNA for amplification. This makes it critical for detecting RNA viruses or gene expression analysis. Both methods require thermal cyclers but target different nucleic acids.
A: Portable RT-PCR systems enable rapid on-site testing, reducing reliance on centralized labs. They are compact, provide real-time results, and are ideal for field diagnostics or resource-limited settings. Their accuracy rivals traditional lab-based systems.
A: Labs prefer RT-PCR when analyzing RNA targets like viral genomes (e.g., HIV, influenza) or measuring mRNA levels. It offers real-time quantification and higher sensitivity than methods like gel-based PCR. It’s also faster for large-scale screening.
A: Proper RNA extraction, reverse transcriptase enzyme quality, and primer design are critical. Contamination control (e.g., UV-treated workspaces) and internal controls minimize errors. Calibration of thermal cyclers ensures consistent amplification.
