GenEx System Aids in the Selection of Reference Genes for Standardizing mRNA Measurements Quantitative real-time PCR (qPCR) is currently the prime technique to measure gene expression. When properly ...

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 ...

Real-time PCR has gained significant acceptance by high-complexity clinical laboratories developing tests for a variety of applications. Sensitivity, automation, and turnaround time have made PCR ...

COVID-19 tests are in greater demand than ever, and new data about the Omicron variant can make picking and using different types of tests confusing. Molecular tests for COVID-19, like the "RT-PCR" ...

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 ...

Bio-Rad Laboratories, Inc. (NYSE: BIO and BIOb) today announced the launch of an RT-PCR kit that allows researchers to simultaneously screen samples for Zika (ZIKV), dengue (DENV1, DENV2, DENV3, DENV4 ...

It’s best to test for RSV soon after your symptoms start. That’s because you’ll likely have the most virus in your system then. As you get better, the amount of virus will go down. (Photo Credit: ...

As SARS-C0V-2 variants emerged, researchers developed a PCR test that uses molecular beacons not only to diagnose COVID-19 infection, but also to identify the specific variant causing that infection.

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 ...
