Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

Researchers used digital polymerase chain reaction assays to measure BRAF V600E or BRAF V600K circulating tumor DNA in ...

Dengue’s rise in 2024, influenced by climate change and shifting serotypes, underscores the need for effective vaccines to ...

View Full Profile. Learn about our Editorial Policies. Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA ...

When the first thermal cyclers for the polymerase chain reaction came out in the 1980s, they were as expensive as a market driven by grant money could make them. Things haven’t got much better ...

Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability helps ...

Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...
