How it Works: Real Time PCR Brendan Maher The instrumentation is basic: a thermal cycler for amplification, a light source for excitation of fluorescent probes (see chemistries below), a camera for ...

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 ...

Since its invention in the 1980s, polymerase chain reaction (PCR) opened the door for applications such as genetic engineering, genotyping, and sequencing, and has become a fundamental part of ...
