7.6.5 PCR "Fingerprinting" (RAPD-PCR)
Variable heating and cooling rates, which can be programmed as desired with
each temperature command,
enable the temperature-control speed to be aligned to the temperature.
With the RAPD-PCR process or with PCR with A/T-rich primer/template hybrids,
it may be necessary to heat
up carefully after annealing.
In the example given, the elongation temperature is attained at a speed
of 1 C/s.
Temperature-control speeds, which may be as
slow as the user desires, can be selected by means of program
loops, with which a gradual change in temperature is obtained via temperature
In the following example, the elongation temperature is raised slowly to
72 C after annealing with the aid of a
