Polymerase chain reaction (PCR)
A technique to amplify a specific target region of DNA in an exponential manner. By heating DNA molecules, the DNA denatures and becomes single stranded, and then by cooling, the DNA anneals to the double stranded again. By using this phenomenon, a single-stranded DNA is used as a template to bind the target primer. The DNA synthesis occurs by repeated cycles of DNA polymerase activity.

Real-time PCR
Real-time PCR is the one of the nucleic acid amplification tests using polymerase chain reaction (PCR) as the basic principle. By the use of oligonucleotide that yields fluorescence after degradation, the fluorescent signal is identified for each PCR cycle, which enables the real-time quantification of the target nucleic acid.

Liquid (nucleic acid) hybridization
After isolating rRNA in a liquid phase, hybridization is performed using a chemiluminescent-labeled DNA probe. After allowing the hybrid to be attached to the separating agent, chemiluminescence detection is performed.
