Evidently, PCR is a highly reproducible and
sensitive technique that can be successfully used in
detecting transgenes for screening GM soybeans and
GM maize (Rhandawa et al., 2006). As the number
of GMO events on the market increases, it is clear
that methods which can detect several targets in a
single reaction, i.e. multiplex detection, is preferable
when enforcing the legislation ruling the occurrence
of GMOs in food (Heide et al., 2008), whereby
multiple targets are amplified in the same reaction
simultaneously.
