Polymerase chain reaction (PCR) technology is a staple of countless research and testing labs, in a range of fields including biomedicine, clinical diagnostics, food microbiology testing and criminal forensics. This fundamental technology uses thermal cycling to facilitate a series of reactions in which a DNA sample is rapidly, exponentially replicated to produce millions or billions of copies of sequence. When acquiring a new PCR system, it is important to consider the end goals of your application, the accuracy and efficiency of the thermal cycling equipment and capacity and flexibility of the instrument. This article gives an overview of different options and features available for PCR systems to help narrow down a suitable system for your application.
