The Epoxy-Activated Beads is a preactivated support that contains high density of

epoxy groups used for immobilization of various ligands. The preactivated support can

be used to immobilize proteins, carbohydrates and various ligands via stable linkage to

amino, thiol and hydroxyl groups. Coupling to hydroxyls is favored at a higher pH of 11-

13, while Thiol-containing ligands are best coupled at pH 7.5-9.0.
