After releasing the genomic DNA by splitting cells with the lysis buffer, the magnetic bead could selectively bind to the genomic DNA in the sample. A small number of impurities that are absorbed by the magnetic bead could be removed by the wash buffer. In TE, the magnetic bead could release the boundgenome DNA, obtaining the high-quality genome DNA. This method is simple and quick and the extracted DNA quality is high, which could meet the requirement for the detection of DNA methylation. Meanwhile, the extraction kit based on the magnetic bead could be compatible with automatic nucleic acid extraction, meeting the high-throughput nucleic acid extraction tasks. Sample requirements 1. The cross contamination between samples should be avoided in the sample collection and storage. 2.The detection shall be completed under the 7-day storage of ambient temperature after the collection of the cervical exfoliated cell sample (non-fixed). The detection shall be completed under the 30-day storage of ambient temperature after the collection of the urine specimen; The detection shall be completed in time after the collection of the cultured cell samples.
