PureCube amine carboxy agarose MagBeads are your best option to couple biomolecules that carry free-standing Amine (NH₂) groups.

• Usage: Coupling proteins to active Epoxy groups
• Specificity: Exposed amine (NH₂) or thiol (SH) groups on biomolecule
• Bead ligand: Chemically active Epoxy groups
• Epoxy group density: 20 µmol/ml
• Bead size: 400 μm
• Filling quantity: Delivered as a 50% suspension
• Storage buffer: 100% isopropanol
• Matrix: 7.5% cross-linked agarose
• Short term storage: In equilibration buffer (see protocol) at 4 °C
• Long term storage: Best lyophilized, or in 100% isopropanol at 4 °C
• Shelf life: If properly stored - six months upon delivery, unopened
• Chemical structure: Epoxy structure

The resulting peptide bond between the Carboxy MagBeads and your biomolecule of interest is stable so that the bead can be used for other applications afterward. Our PureCube carboxy MagBeads are also available as agarose resin in case you prefer this purification method or as normal-sized MagBeads if you would like to have more surface area on your beads.
