PureCube Epoxy Activated MagBeads XL is your best option to couple biomolecules that carry free-standing amine (NH₂) and thiol (SH) groups.

• Usage: Coupling biomolecules 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: 90 μm
• Filling quantity: Delivered as a 25% suspension
• Storage buffer: 100% isopropanol
• Matrix: 6% cross-linked agarose
• Short term storage: In equilibration buffer (see protocol) at 4 °C
• Long term storage: In 100% isopropanol at 4 °C
• Shelf life: If properly stored - six months upon delivery, unopened
• Chemical structure: Epoxy structure

The resulting amide and thiol bond between the Epoxy MagBeads and your biomolecule of interest is stable so that the bead can be used for other applications afterward. Our PureCube Epoxy Activated MagBeads XL are also available as agarose resin in case you prefer FPLC or batch spin methods or as MagBeads with a smaller bead diameter if your downstream application requires more mechanically stable beads.
