Perkenalan
- Magnetic bead nucleic acid purification technology utilizes nano or micron superparamagnetic material as the matrix, often using black or yellowish-brown ferric oxide.
- The surface of the beads is coated with functional groups such as carboxyl, hydroxyl, or silicon groups, which facilitate nucleic acid adsorption.
- Silicon-based magnetic beads are the most common, working similarly to classical glass milk or glass fiber filter membrane purification methods.
- Magpure particles are polydisperse silica magnetic beads, comprising 50% ferric oxide at the core and 50% silica on the surface.
- This product serves various purposes including plasmid extraction, gel DNA recovery, product purification, genomic DNA and Ekstraksi RNA, as well as viral nucleic acid extraction.

Prinsip
- High salt mediated binding: Magpure particles can selectively recover DNA molecules in solutions containing 2-4M guanidine isothiocyanate, while impurities like protein polysaccharides are not adsorbed.
- Alcohol-mediated binding: Magpure particles can selectively recover DNA/RNA molecules in solutions containing guanidine salt and alcohol (>25%), with proteins and other impurities not being adsorbed.
- After treating biological samples with a digestive solution or lysis buffer, DNA/RNA is released into the reagents from cells, organelles, and protein complexes (ribosomes and nucleosomes).
- Upon adding Magpure particles and binding solution, DNA/RNA adheres to the surface of the particles, forming the DNA/RNA bead complex.
- The magnetic field then separates and collects the magnetic beads, removing impurities such as protein with the waste liquid.
- Following two or three additional cleaning steps, the DNA/RNA magnetic bead complex is resuspended in sterilized water or TE buffer.
- DNA/RNA falls off from the surface of the magnetic beads, achieving purification.
