Our Technology

The new Aurosphere superparamagnetic particles from Magnostics Ltd, represent a breakthrough of performance in magnetic separation - the magnetic content of these particles is significantly higher and more uniform than has been previously available. The strong magnetic force makes them highly effective in purifying proteins and cells at fast speed with minimum loss and indirect handling of viscous solutions. The particles are conveniently functionalized with a dense layer of functional groups that makes them easy for conjugation, stable in physiological salt solution and low in nonspecific adsorption. The unique properties of these particles make it possible to perform demanding separations from large volumes (e.g. fermentation broths), high viscosity solutions (e.g. serum or whole blood), or in applications where efficiency matters.
