The PocketPCR is a low-cost, small size thermocycler capable of activating biological reactions such as polymerase chain reaction (PCR). PCR is a method widely used in molecular biology to make copies of a specific DNA segment. Applications of the technique include DNA cloning for sequencing, analysis of genetic fingerprints, amplification of ancient DNA and gene cloning.
