What is real-time quantitative PCR? qPCR uses one of two methods to detect the changes to DNA amplification: use of fluorescent dyes or sequence-specific DNA probes. qPCR is normally performed in a ...

Real-time PCR, or quantitative qPCR, is a commonly used molecular biology lab technique to determine the actual amount of PCR product at a given cycle. For quantitative reverse transcription PCR ...

Over the past decade, PCR testing for infectious agents in the clinical laboratory has begun to replace other methods, such as culture. PCR is often now referred to as the gold standard in this field.

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 ...

Polymerase Chain Reaction (PCR) is a method which utilizes the mechanism of DNA replication to amplify a specific part of DNA. This involves the use of DNA polymerase, which makes new strands of DNA ...

Indirect fluorescent antibody (IFA) assay and reverse transcription-polymerase chain reaction (RT-PCR) are two current methods commonly used for the detection of infectious bronchitis virus (IBV) and ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

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 ...

HOUSTON--(BUSINESS WIRE)--Quantabio, a leading provider of robust DNA and RNA amplification reagents for the most demanding molecular testing and life science research applications, today announced ...

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 ...
