Plant food * (magnetic bead method)

• Using CTAB formula combined with magnetic bead nucleic acid extraction method to remove a certain amount of interference from PCR inhibitors
• Organic solvent components without benzene and chlorine
• Micro magnetic beads actively bind to nucleic acids, effectively improving nucleic acid recovery and repeatability
• Suitable for DNA detection of genetically modified and plant derived deep processed samples
• High DNA yield and purity: corn powder 500ug/ml, soybean powder 2000ug/ml, A260/A280 >1.8

Deep processed foods not only have a wide range of sources and complex matrices, but also mostly contain PCR inhibitors, which can easily interfere with PCR experimental results and lead to false negative problems. The use of magnetic bead processing technology can not only ensure the recovery rate, repeatability, and quality of nucleic acid extraction to a considerable extent, but also help significantly remove the influence of PCR inhibitors. Combined with the large capacity 50ml notched centrifuge tube of the temperature controlled rotary incubator, it can provide 1-20g large sample DNA extraction service for food testing, reducing the missed detection rate caused by sampling errors.
