ExtraMag Amino Beads for immobilization of proteins, peptides, carbohydrates, glycoproteins and glycolipids

ExtraMag Amino beads are amino functionalized magnetic particles designed for the immobilization of bioactive molecules for sample preparation, proteomics and immunoassay applications.

  1. Covalent binding of the ligands with carboxyl groups using carbodiimide as cross-linker
  2. Immobilization of proteins and peptides
  3. C-terminal coupling of peptides
  4. Covalent binding of aldehydes or ketones
  5. Covalent binding of carbohydrates, glycoproteins and glycolipids


  1. Superparamagnetic particles with high magnetization
  2. High density of amino groups on the surface
  3. Reduced nonspecific sorption
  4. Fast and simple protocols
