NeutrAvidin™ UltraLink™ resin is a beaded polyacrylamide resin of immobilized NeutrAvidin™ Protein, a modified form of avidin with exceptional biotin-binding characteristics for affinity purification methods.

• UltraLink beads are hydrophilic, charge-free, highly crosslinked, rigid and durable
• Acrylamide-based support provides an alternative to crosslinked beaded agarose supports for medium-pressure applications

NeutrAvidin™ UltraLink™ resin consists of a specially purified and deglycosylated form of avidin that has been covalently immobilised onto a beaded acrylamide support. Compared to native avidin, NeutrAvidin™ Protein is more neutral and exhibits much less non specific binding properties in biotin-binding applications. UltraLink beads are hydrophilic, charge-free, highly crosslinked, rigid and durable. These properties make the affinity resin suitable for a variety of batch- or column-type affinity procedures that require medium-pressure chromatography.

NeutrAvidin™ UltraLink™ resin binding capacity: 12 - 20 µg biotin/mL of settled resin

NeutrAvidin™ Plus UltraLink™ resin binding capacity: >30 µg biotin/mL of settled resin
