Principle
Magnetic Separation:
- Magnetic beads with silica coating are used.
- After lysing the sample, DNA/RNA is released.
- Magnetic beads and binding solution are added.
- DNA/RNA binds to the surface of the beads.
- A magnet separates the bead-DNA/RNA complex from the solution (impurities).
Selective Binding:
- High salt-mediated binding (2-4M guanidine isothiocyanate): selectively recovers DNA molecules.
- Alcohol-mediated binding (guanidine salt and >25% alcohol): selectively recovers DNA/RNA molecules.
- Proteins and other impurities are not adsorbed to the beads.
Elution:
- The purified DNA/RNA complex is washed to remove contaminants.
- DNA/RNA is released from the beads using sterilized water or TE buffer.
