Description
SP Cross-linked Agarose Big Beads are strong ion exchangers designed for industrial applications. The large particle sizes (100-300 µm) and excellent physical stability of the base matrix ensures maintained speed, even with viscous samples. SP Cross-linked Agarose Big Beads are therefore the ultimate ion exchange media for initial purifications when high viscosity precludes the use of ion exchangers with smaller bead size, such as Cross-linked Agarose Fast Flow ion exchangers. The unique flow characteristics are also invaluable when adsorption needs to be done quickly.

Q Cross-linked Agarose High Performance has well-deserved reputations as highly successful anion and cation ion exchange media for purifying a wide range of biomolecules.
Amino Acid Agarose
Used in proteomics and protein chromatography, amino acid agarose is prepared by covalently coupling of amino acid through a 17 atom stable and uncharged ether hydrophilic linkage to highly cross-linked 6% agarose with bead mean diameter of 90 um.
Epoxy-activated Agarose for Ligand or Protein Coupling
Epoxy-activated Agarose is a pre-activated affinity chromatography support for the immobilization of a variety of biomolecules that contain nucleophiles, such as hydroxyl, amino, or thiol groups. These groups couple to the epoxy groups on the support, which is then used for the purification of proteins, carbohydrates, or DNA.
