Magnetic particle technologies

The particles used in the sbeadex™ and mag kits are modified superparamagnetic particles, which allow efficient and high quality purification of small and large DNA fragments. These allow efficient and high quality purification of small and large nucleic acid fragments of several sample materials. The beads are attracted by strong permanent magnets, but they do not become permanent magnets.

Parameters of the magnetic particles:

Colour Dark brown
Size < 53 µm, 80% 5-10 µm
Shape irregular
Specific weight 3.0 – 3.5 g / 10 mL dry particles
Maximum capacity 2 µg DNA / mg particles
Storage/stability > 2 years as dry powder at room temperature (normally the beads are delivered as suspension which is stable approx. 6 months)
