Discussion
Using the iCycler iQ and the Amplifluor universal amplification and detection
systems, it was possible to detect and quantitate GM soy DNA present in
both in-house and commercially available standards to a high degree of
accuracy. Extension of this technology to the determination of GM soy
content in foodstuffs is straightforward, and by changing the primers
used in each step of the process, levels of GM maize or other GMOs can
be determined. Indeed, since the iCycler iQ and the Amplifluor systems
are multiplex compatible, the development of assays to detect 2 or more
targets simultaneously is an area we are actively pursuing.
