Dynabeads Products & Technology
Applied Biosystems™ Dynabeads™ and Invitrogen™ Dynabeads™ magnetic separation is gentle and tube-based. No columns or centrifugations are necessary. The true uniformity of bead size, shape and surface area provides optimal accessibility and rapid liquid-phase reaction kinetics. You can reduce variability and get more reliable and reproducible results for your purifications and your analyses.

Dynabeads technology for magnetic bead separation
Magnetic particles (Figure 1) from alternative suppliers often have a random size range and surface area that could compromise the reproducibility of your results.

Characteristics of Dynabeads
- Dynabeads are superparamagnetic particles, meaning that they exhibit magnetic properties when placed in a magnetic field with no residual magnetism once removed from the magnetic field
- Unique batch-to-batch reproducibility secures reproducible, quality results
- Spherical shape and defined surface chemistry minimize chemical agglutination and non-specific binding
- The polymer shell on each bead protects your target from toxic exposure to iron
- Bioreactive molecules can be adsorbed or coupled to their surface, and used to separate biological materials (cells, proteins, nucleic acids, etc).
