Abstract. Polymerase chain reaction (PCR) is the most widely used nucleo-based method for the detection of plant viruses. It is a primer-mediated in vitro reaction involving amplification of target nucleic acid sequences. A standard PCR is a three-step procedure: (1) denaturation at a high temperature (90–95 °C), (2) annealing of target ...

The global polymerase chain reaction market size was valued at USD 36.84 billion in 2022 and is expected to expand at a compound annual growth rate (CAGR) of -9.30% from 2023 to 2030. A significant decline in the industry growth is anticipated to decrease the demand for diagnostic tests for COVID-19 infection during the forecast period.

A standard Polymerase Chain Reaction (PCR) is an in vitro method that allows a single, short region of a DNA molecule (single gene perhaps) to be copied multiple times by Taq Polymerase. From a single copy of DNA (the template), a researcher can create thousands of identical copies using a simple set of reagents and a basic heating and cooling ...

The polymerase chain reaction (PCR) underlies almost all of modern molecular cloning. Using PCR, a defined target sequence that occurs once within a DNA of high complexity and large size—an entire mammalian genome, for example—can be rapidly and selectively amplified in a quasi-exponential chain reaction that generates millions of copies. ...
