ExtraMag Carboxy Beads for immobilization of proteins, nucleic acids and other bioactive compounds

ExtraMag Carboxy beads are carboxyl functionalized magnetic particles 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 carboxyl groups on the surface
  3. Reduced nonspecific sorption
  4. Fast and simple protocols
