Thermo Scientific™ NAb™ Protein A Plus Spin Columns, 1 mL

Description

• Thermo Scientific™ Pierce Protein A Plus Agarose is a versatile, high-performance affinity resin for antibody purification that is available as bottled agarose beads, pre-packed spin columns, 96-well filter plates and complete IgG purification kits
• Pierce Protein A Plus Agarose consists of purified native Protein A that has been covalently immobilized at high density onto high-quality crosslinked 6% beaded agarose (CL-6B)
• Among the many available forms of immobilized Protein A affinity resin, this premiere variety provides the most versatile combination of chromatographic features for high yield and high purity purification of whole IgG from mammalian serum samples
• The agarose beads have physical and chemical properties suitable for many affinity purification systems
• Accordingly, Pierce Protein A Plus Agarose is offered in several convenient package formats, including bottled resin slurries, three sizes of spin columns, complete purification kits, two sizes of FPLC-ready chromatography cartridges, and 96-well filter plates
• Protein A is a bacteria-derived protein that binds with high affinity and specificity to the Fc portion of antibodies, especially those of the IgG class
• Compared to its alternative (Protein G), Protein A provides the highest binding capacity for subclasses of IgG from rabbits, pigs, dogs and cats
• Protein A also has higher binding capacity for human IgG, except for IgG3, which it binds weakly
• Protein A binds weakly to mouse IgG1 and is not recommended for most applications with that antibody isotype
• Highlights: Native Protein A – immobilized Protein A is ideal for polyclonal IgG purification from human, rabbit, pig, dog or cat serum Agarose resin – support is crosslinked 6% beaded agarose (CL-6B), the most popular resin for protein affinity purification methods Inert and stable – superior manufacturing method immobilizes Protein A by charge-free, leach-resistant covalent bonds, resulting in low nonspecific binding and enabling multiple uses without decline in yield High capacity – “Plus” variety of Pierce Protein A Agarose has a dense load of immobilized Protein A, providing a binding capacity greater than 34mg human IgG/mL resin (approx
• 16 to 17mg mouse IgG/mL resin) Multiple formats – choose from bottled resin slurries, centrifuge-ready columns, complete purification kits, two sizes of FPLC-ready chromatography cartridges, and 96-well filter plates Properties of crosslinked 6% beaded agarose (CL-6B): Support pH Stability: 2 to 14 (short term); 3 to 13 (long term) Average Particle Size: 45 to 165 microns Exclusion Limit: 10,000 to 4,000,000 daltons Maximum Volumetric Flow Rate: approx
• 1mL/minute (for 1cm diameter column) Maximum Linear Velocity: 30cm per hour Maximum Pressure: less than 25psi (1.5 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.) Available Formats: Resin Slurries: 1mL, 5mL, 25mL bottles Spin Columns: 0.2mL (microcentrifuge), 1mL, 5mL columns Purification Kits: complete kits in all three column sizes Chromatography Cartridges - compatible with automated liquid chromatography systems and with syringe processing 96-well Spin Plates: pre-dispensed 96-well filter plates, compatible with centrifugation and vacuum manifold systems for manual or automated purification
• The plates enable fast, consistent well-to-well and plate-to-plate reproducibility for small-scale, high-throughput separations Bulk and Custom: let us know your needs for bulk Pierce Protein A Plus Agarose Includes: Purification kits contain Protein A Plus Spin Columns, binding buffer, elution buffer and neutralization buffer
