چکیده
The real-time polymerase chain reaction (real-time PCR) is a recent modification to PCR (UNIT 10.2) that is rapidly changing the nature of how biomedical science research is conducted. It was first introduced in 1992 by Higuchi and coworkers and has seen a rapid increase in its use since (Higuchi et al., 1992, 1993). Real-time PCR allows precise quantification of specific nucleic acids in a complex mixture even if the starting amount of material is at a very low concentration. This is accomplished by monitoring the amplification of a target sequence in real-time using fluorescent technology. How quickly the amplified target reaches a threshold detection level correlates with the amount of starting material present.
