[Infographic] The 7 Sins of GMO Testing
The 7 Sins of GMO Testing
- Identifying the wrong target
Know the events and proteins that comprise your target to avoid false positives and erroneous results. - Choosing the wrong method
DNA-based methods test for different targets than protein-based methods. Depending on the sample, they may deliver different results. - Not understanding the different degrees of test sensitivity
DNA-based methods are very sensitive and can detect a single copy of the target gene in the sample. Protein-based methods may require more test runs to guarantee a result. - Removing impurities or treating the sample
No washing, cleaning or heating the sample! If you do, you run the risk of removing traces of GM plants and ending up with inaccurate test results. - Using an improper procedure to prepare your sample
Proper cleaning of equipment avoids cross-contamination, and grinding samples to the right size ensures that lateral flow devices (LFDs) will work as expected. Even the shape of the extraction vessel is important. - Customizing testing procedures
Avoid this sin by reading and following the directions on the package insert. Ensuring your staff is trained in laboratory procedure can safeguard your testing process. - Insufficiently cleaning your equipment
Prevent cross-contamination by washing every component of your equipment – mill blades, jars, blenders – with liquid soap. Rinse them with water and handle all samples with gloves. Make sure your cleaning procedure is validated.
