The Perkin-Elmer/ Cetus DNA Thermal Cycler automates the polymerase chain reaction (PCR) technique for amplifying specific DNA sequences. A microprocessor allows you to create programs consisting of time and temperature reaction parameters for individual PCR reactions. These programs can be stored in files which may be modified further for different reactions. In addition, files may be linked together, allowing for more complex programs or “soaking” at 4 degrees C after completion of cycling when reactions are performed overnight.
