PCR診斷試劑盒及冷凍干燥的一些考慮
Polymerase chain reaction (PCR) is a method widely used in molecular biology to make many copies of a specific DNA segment. PCR enables a small amount (as low as a single copy) of DNA of a particular target/test sample to be exponentially amplified to generate thousands to millions more copies of that particular DNA segment. A precursor reverse transcript process (RT-PCR) can also be added if the target sample is RNA. The RT process first converts the RNA to DNA, and then the PCR process follows with DNA amplification.
