Description

Thermo Scientific Pierce Protein A Plus UltraLink Resin is an extremely durable beaded polyacrylamide support to which IgG-binding Protein A has been immobilized at high density for use in IgG purification methods.

Features of Protein A Plus UltraLink Resin:

Immobilized Protein A – specifically binds IgG from several mammalian species, especially most subtypes of human and rabbit IgG
High capacity – this “Plus” variety has a dense load of immobilized Protein A, providing a binding capacity of at least 30 mg human IgG per milliliter of resin
UltraLink Resin – acrylamide-based support provides an alternative to crosslinked beaded agarose supports for medium pressure applications

Protein A Plus UltraLink Resin is used for high-capacity binding and purification of IgG in gravity-flow, spin-column or medium-pressure chromatography methods. Protein A is a popular antibody-binding protein that is especially useful for purification of IgG from rabbit or human serum.

Protein A is a cell wall component produced by several strains of Staphylococcus aureus. The 46.7kDa-protein consists of a single polypeptide chain that is essentially devoid of carbohydrate. Native Protein A has contains four high-affinity (Ka = 10^8/mol) binding sites that are capable of interacting with the Fc region of IgG-class antibodies from selected mammalian species. IgG-binding function is optimal at pH 8.2, but efficient binding also occurs in neutral and physiological buffers (pH 7.0 to 7.6).

UltraLink Resin is an azlactone-activated polyacrylamide support that is hydrophilic, charge-free, high capacity, highly crosslinked, rigid and porous. This support is especially useful for medium pressure techniques when using large sample volumes requiring fast-flow techniques (FPLC) and large-scale applications. Unlike typical beaded agarose supports, UltraLink Support does not crush or collapse when subjected to high flow rates that result in pressures exceeding 25psi.

Properties of Thermo Scientific UltraLink Resin:
• Support pH Stability: 1 to 13
• Average Particle Size: 50 to 80 microns
• Exclusion Limit: greater than 2,000,000 daltons
• Average Surface Area: greater than 250m2 per gram of beads
• Average Pore Volume: greater than 1.2 mL per gram of beads (> 60% of bead volume)
• Pore Size: 500 to 1000 angstroms (50 to 100nm)
• Maximum Linear Velocity: 3000 cm per hour
• Maximum Pressure: 100psi (6.9 bar), defined as the maximum pressure drop across a column that the resin can withstand (Note: The indicated gauge pressure of a liquid chromatography apparatus may be measuring the total system pressure rather than the pressure drop across the column.)
