Perform a variety of antibody affinity purification methods with Thermo Scientific™ Pierce Protein A Agarose, a standard-capacity Protein A beaded agarose resin.
Pierce Protein A Agarose consists of purified native Protein A that has been covalently immobilized onto high-quality crosslinked 6% beaded agarose. The agarose beads have physical and chemical properties that enable them to be used in a variety of batch- or column-type affinity purification procedure. Several package formats are offered: 5mL and 25mL bottles of resin slurry, 1mL pre-packed columns and a complete IgG purification kit.
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 also binds weakly to mouse IgG1 and is not recommended for most applications with that antibody isotype.
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
Standard capacity – Pierce Protein A Agarose has a normal load of immobilized Protein A, providing a binding capacity of 12 to 19mg human IgG/mL resin (approx. 6 to 8mg mouse IgG/mL resin)
Properties of crosslinked 6% beaded agarose (CL-6B):
Kit contains Protein A Column (1mL each), Protein A IgG Binding Buffer, IgG Elution Buffer and desalting columns
