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.

The tightly controlled Dynabeads® production processes give uniform spherical beads, with highly defined and consistent product characteristics. By reducing particle variability, you get truly reliable and reproducible results on which to build your studies, diagnostic assays and therapeutic protocols.

The level of reproducibility within and between batches of Dynabeads® is quite unique. The same surface area is offered for each experiment, ensuring the best efficacy and reproducibility for your analyses.

Superior quality and reproducibility has always been the hallmark of Dynabeads®

Characteristics of Dynabeads®

Dynabeads® separation is gentle and based on liquid-phase kinetics. No columns or centrifugations are necessary
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
True uniformity (CV<3%) of size, shape and surface area provides optimal accessibility and reaction kinetics, for rapid and efficient binding
Unique batch-to-batch reproducibility (typically within 5%) 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).
