Polymerase chain reaction system

Abstract

The present invention relates to a system structure capable of performing real-time detection of nucleic acid extraction and amplification reactions and amplified results in a device for implementing a polymerase chain reaction (PCR). A PCR system includes a nucleic acid extraction cartridge configured to extract a nucleic acid of a biological sample via a nucleic acid extraction reagent stored therein and form a PCR preliminary mixture by being additionally mixed with a polymerase reaction dried product, a PCR plate inserted into the nucleic acid extraction cartridge, having a channel coupled to the nucleic acid extraction cartridge, and receives a nucleic acid solution or the PCR preliminary mixture extracted from the nucleic acid extraction cartridge and diversely accommodates a PCR reaction dried product containing a dried primer/probe or a primer/probe in at least one reaction well, a temperature control module disposed above the PCR plateand including a pair of heating blocksandadjacent to the reaction well (W) to apply different temperatures, and a scanning module scanning a concentration of a reactant amplified in the reaction well (W).
