Real-time polymerase chain reaction detection methods

Real-time Polymerase Chain Reaction (PCR) is a quickly developing technology that has built upon the classic end-point PCR detection methods. In this article, we will review recent patents related to various chemistries used for nucleic acid detection during real-time PCR amplification. Real-time assay chemistries are subdivided into several main categories including DNA-binding agents, molecular beacons, hybridization probes, hydrolysis probes, and dye-primer based systems. Specific advantages and applications of each category are highlighted herein.
