CDI activated (Agarose) 4B, 25 ML

Price$ 278.51
  • SKU: C-2885-25ML
  • Pack Size: 25 ML




  • Pre-activated medium for immobilization of ligands containing primary amines.
  • N, N`-Carbonyl diimidazole (CDI) mediated activation of Separopore® 4B matrix to allow coupling of the primary amino ligands by a stable amide bond formation.
  • No charge is introduced into the matrix after the coupling reaction.
  • No ligand leakage after coupling.
  • Superior stability: Activated matrix is much more resistant to hydrolysis.
  • Ideal for immobilization of large protein ligands such as antibodies as well as peptides and nucleic acids.
  • Coupling reaction can also be carried out in organic solvents.
  • High coupling efficiency and easy to handle.
  • CDI-activated Separopore® 4B is activated with CDI groups for covalent immobilization of proteins and other molecules that contain N-nucleophiles.
