MoBiTec introduces a new product line of magnetic silica beads that are specifically designed for separation, concentration and purification of biomolecules, specific cells or cell compartments. They are ideally suited as a solid phase in assay kits. Due to a fast and flexible production process unrestricted customization possibilities with regard to sizes, kinetics, optical, surface and binding properties is facilitated.


  • highly monodisperse
  • no aggregation
  • adjustable magnetic moments
  • adjustable surface properties
  • efficiently automatable
  • neutral optical properties

Due to these features magnetic silica particles are very flexible tools for research & developmental uses such as cell separation & expansion, proteomics, nucleic acid isolation and IVD assay development. They are available in different diameters, with various encapsulations and a number of coatings for further conjugation e.g. with biomolecules.
