"WebbThese approaches rely on algorithms to model the amplification plot curves and so are dependent on the number of cycles over which there is an increase in fluorescence. These are most likely to succeed when the measurement is made using a DNA-binding dye or Scorpions ® Probes since these assays yield a greater change in fluorescence per cycle.
