Food ingredients are very complex including many additives such as salt, sugar, oil, food colorings, etc. In addition, the procedures including frying, cooking, toasting, etc. may do different damages to DNA in raw materials to some extent. The isolation of DNA from food is more difficult process than from raw materials.

The kit adopts unique buffer system and is suitable for purification of DNA from a variety of deep-processed food. The kit avoids the use of hazardous organic solvents such as phenol-chloroform for most samples and removes the vast majority of proteins, fat and other organic purities.

The DNA purified from deep-processed food can be used in a variety of experiments including PCR and real-time PCR.

Processed Food DNA Extraction Kit should be kept in dry place and can be stored at room temperature (15-30°C) for up to 15 months without showing any reduction in performance and quality. If any precipitate forms in the buffers, it should be dissolved by warming the buffers at 37°C before use.

● Some samples such as soy sauce and tomato ketchup have to be pretreated to acquire optimal results. Please inquire us directly for special samples before DNA extraction.

● If precipitate have formed in Buffer GMO1, Incubate the buffer at 37°C to re-dissolve and mix by vortex before use.

● All the steps should be performed on table centrifuge at room temperature (15-30°C).
