MagPure Particles F

MagPure Particles F are developed for high-efficiency nucleic acid purification from large-volume genomic DNA/RNA, especially circulating DNA (cfDNA) samples. The system is optimized to support consistent recovery of fragmented DNA from plasma inputs where maximizing yield is critical.

The magnetic bead surface and binding conditions are designed to maintain stable adsorption across varying sample volumes, enabling reliable performance in workflows involving increased plasma input or low-abundance nucleic acids.

Compared with small-volume extraction systems, MagPure Particles F provide improved recovery efficiency in larger input workflows. For applications involving limited sample input or smaller plasma volumes, MagPure Particles G may be considered as an alternative solution.

Principle

Highsalt mediated binding: in the solution containing 2-4M guanidine isothiocyanate, Magpure particles can selectively recover DNA molecules, and impurities such as protein polysaccharides are not adsorbed.

Alcohol mediated binding: in the solution containing guanidine salt and alcohol (>25%), Magpure particles can selectively recover DNA/RNA molecules, and proteins and other impurities are not adsorbed.

After biological samples are treated with digestive solution or lysis Buffer, DNA/RNA is released from cells, organelles and protein complexes (ribosomes and nucleosomes) into reagents. After Magpure particles and binding solution are added, DNA/RNA is adsorbed to the surface of Magpure particles to form DNA/RNA bead complex. Under the action of the magnetic field, the magnetic beads are separated and collected, and the impurities such as protein are removed with the waste liquid. After two or three steps of further cleaning, the DNA/RNA magnetic bead complex is resuspended in sterilized water or TE buffer, and the DNA/RNA falls off from the surface of the magnetic beads, so as to achieve the purpose of purification.
