The Wizard® Magnetic DNA Purification System for Food purifies DNA from a variety of food samples including corn seeds, cornmeal, soybeans, soy flour and soy milk. Processed food, such as corn chips, chocolate and chocolate-containing foods, lecithin and vegetable oils may also be used with protocol variations. The DNA purified from these samples can be used in PCR-based testing for genetically modified organism (GMO) DNA sequences.

This food DNA purification kit uses paramagnetic particles for DNA isolation. Unlike column-based systems, binding of nucleic acids to magnetic particles can occur in solution, resulting in increased binding kinetics and efficiency. Particles also can be completely resuspended during the wash steps of a purification protocol, thus enhancing contact with and removal of contaminants, and increasing nucleic acid purity.

The convenient protocol generates results in one-third of the time of traditional methods.
