Nucleic Acid Extraction Kit (A02)

Short Description:

Intended use

The kit utilizes the magnetic bead that could specifically  bind to nucleic acid, and the unique buffer system. It is applicable to the nucleic acid extraction, enrichment, and purification of cervical exfoliated cells, urine specimens, and cultured cells. The purified nucleic acid could be applied to the Real-time PCR, RT-PCR, PCR, sequencing and other tests. The operators should have professional training in molecular biological detection and be qualified for relevant experimental operations. The laboratory should have reasonable biological safety precautions and protective procedures.

Detection principle

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.

About Us

As a high-tech enterprise founded in 2018 by top epigenetic experts, Epiprobe focuses on the molecular diagnosis of cancer DNA methylation and precision theranostics industry. With a profound technology basis, we aim to lead the era of new products to nip cancer in the bud!

Based on Epiprobe core team’s long-term research, development and transformation in the field of DNA methylation with the cutting-edge innovations, combined with the unique DNA methylation targets of cancers, we use a unique multivariate algorithm combining big data and artificial intelligence technology to independently develop an exclusive patent-protected liquid biopsy technology. By analyzing the methylation level of specific sites of free DNA fragments in the sample, the shortcomings of traditional examination methods and the limitations of surgery and puncture sampling are avoided, which not only achieves accurate detection of early cancers, but also enables real-time monitoring of cancer occurrence and development dynamics.
