DNA Extraction/Genomic DNA Purification
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.
