• Matrix: 7.5% 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 - 3 years upon delivery, unopened
• Chemical Structure: Amine structure

The resulting peptide bond between the Amine Agarose beads and your biomolecule of interest is stable so that the bead can be used for other applications afterward. Our PureCube Amine Activated Agarose is also available as magnetic beads if you prefer this purification method or as XL agarose resin if you need higher flow rates for your downstream application.
