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

• Usage: Coupling proteins to active Amine Groups
• Specificity: Exposed carboxy (COOH) groups on biomolecule
• Amine group density: Higher than 20 µmol/ml
• Bead ligand: Chemically active Amine groups
• Bead size: 30 μm
• Filling quantity: Delivered as a 25% suspension
• Storage buffer: 100% isopropanol
• Matrix: 6% cross-linked agarose
• Short term storage: In neutral buffer at 4 °C
• Long term storage: 100 mM sodium hydrogen carbonate, 0.02% sodium azide, pH 7.5 at 4 °C or 20 mM sodium acetate, 20% ethanol, pH 6.5 at 4 °C
• Shelf life: If properly stored - three years upon delivery, unopened
• Chemical structure: Amine structure

The resulting peptide bond between the Amine MagBeads and your biomolecule of interest is stable so that the bead can be used for other applications afterward. Our PureCube Amine Activated MagBeads are also available as agarose resin if you prefer this purification method or as XL MagBeads if your downstream application involves more viscous cell media.
