Polymerase chain reaction, or PCR, was developed to identify a small fragment of a virus and create multiple copies, making detection easier. PCR is the gold standard in testing for COVID-19 and other ...

One of the best ways to figure out how far a virus like COVID-19 has spread in a community is to test for it. This step-by-step guide explains how coronavirus swab-the-nose-and-throat tests work, and ...

Kary B. Mullis, Nobel Laureate in Chemistry, died Aug. 7 of pneumonia at the age of 74. He won the 1993 Nobel Prize in Chemistry for his invention of the polymerase chain reaction (PCR) method for ...

A team of UK-based scientists has recently developed an allele-specific probe polymerase chain reaction method that can accurately detect different variants/lineages of severe acute respiratory ...

With the emergence of the Omicron variant of concern (VOC) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes the coronavirus disease 2019 (COVID-19), new and ...

A digital polymerase chain reaction (dPCR) technique for screening malaria parasite genomes will help identify when they have mutations that allow them to dodge detection by some rapid tests, shows a ...

A recent McKnight’s article on a new consensus statement recommending against PCR urine testing in long-term care raises valid concerns about inappropriate use, particularly when results are ...

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing ...

PCR genetic analysis has been in the spotlight since COVID-19, but light is now further facilitating PCR-free methods. Osaka Metropolitan University scientists have developed a light-induced DNA ...
