Detection techiniques for presence of GMO foods

1. Protein-based GMO detection

• strip test
• ELISA

2. DNA-based GMO detection

• qualitative PCR
• quantitative PCR
• microaray

for pictures, you can take a look at this link: http://www.economia.uniroma2.it/conferenze/icabr2005/papers/De_Leo_F_paper_1.pdf

pg 14.

detection limits are in the range of 20pg to 10ng of target DNA and 0.0001-1% of the mass fraction of GMOs. DNA-based GMO detection depends on the complementarity of the DNA double helix that hybridize in e sequence-specific manner.
