Food DNA Extraction Kit (FGD100, FGD300)
The Presto™ Food DNA Extraction Kit is designed for rapid isolation of DNA from a variety of raw and processed food samples. The unique food lysis buffer (containing nonionic detergent CTAB) when combined with Proteinase K is used to digest food tissue and proteins. PCR inhibitors such as polysaccharides and plant metabolites are removed by centrifugation. Chloroform treatment, separates residual inhibitors from the clear supernatant in the organic phase. DNA in the aqueous phase is then bound by the GD Column followed by wash and elution. DNA phenol extraction or alcohol precipitation is not required and the entire procedure can be completed within 60 minutes. The purified genomic DNA is ready for use in PCR, restriction enzyme digestion, and sequencing reactions.

Quality Control

The quality of the Presto™ Food DNA Extraction Kit is tested on a lot-to-lot basis by isolating genomic DNA from 200 mg food samples. Following the purification process, the purified genomic DNA (A260/A280 ratio 1.8-2.0) is analyzed by electrophoresis.
 
Presto™ Food DNA Extraction Kit Functional Test Data
Figure 1. Total DNA was purified from 200 mg of sausage using the Presto™ Food DNA Extraction Kit. 10 μl aliquots of extracted DNA from a 100 μl eluate was analyzed on a 0.8% agarose gel.
