Thermo Scientific™ Pierce™ NeutrAvidin™ UltraLink™ Resin

Thermo Scientific 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.

NeutrAvidin UltraLink Resin consists of a specially purified and deglycosylated form of avidin that has been covalently immobilized onto a beaded acrylamide support. Compared to native avidin, NeutrAvidin protein is more neutral and exhibits much less nonspecific 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. The resin provides an alternative to agarose supports when situations demand it. Generally, NeutrAvidin products function as well or better than their streptavidin counterparts and are less expensive.

Features

• NeutrAvidin protein—purified, deglycosylated avidin protein (60kDa, pI 6.3); tetrameric with four biotin-binding site per molecule
• UltraLink Resin—acrylamide-based support provides an alternative to crosslinked beaded agarose supports for medium-pressure applications
• Standard capacity—this variety of beads has a normal load of immobilized NeutrAvidin protein, providing a binding capacity of 1 to 2 mg of biotinylated BSA per mL of resin
