Epoxy Beads for immobilization of proteins, nucleic acids and bioactive compounds

ExtraMag Epoxy beads are polymer shell covered magnetic particles with epoxy groups designed for the immobilization of bioactive molecules for sample preparation, proteomics, nucleic acid isolation and immunoassay applications.

  1. Immobilization of primary amines using carbodiimide as cross-linker
  2. Immobilization of proteins and peptides
  3. Immobilization of amino-modified oligonucleotides

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