Real-time PCR is a useful tool that uses the standard principles of polymerase chain reaction (PCR) coupled with fluorescent dye(s) for detection and quantification of a sequence of DNA. While there are many advantages to using real-time PCR over standard PCR, there is still a lot to think about when it comes to purchasing a thermal cycler specific to real-time PCR. Specifications that might weigh into your decision could be dynamic range, excitation and detection methods, and of course, price. You'll also want to consider the ease-of-use of the software, and instrument set up. There are numerous real-time PCR systems available today. You can find the one that's right for you by first checking the specifications and then requesting a demo from the vendor. Begin your search by checking out the products listed below.
