Antibody Purification Resins

Reducing time and simplifying the purification process is possible with Protein A Magnetic Beads and Protein G Magnetic Beads. As an alternative to an agarose matrix, these 1µm coated Fe₃O₄ beads are ideal for immunoprecipitations, co-immunoprecipitations, ChIP, protein isolation, and small-scale IgG purification.

The Pearl™ line of purification reagents were optimized to make your purification clean, fast, and physiologically relevant. Ensure your antibody is in an optimal buffer and free from interfering agents with the Pearl™ Antibody Clean Up Kit.  Rapidly purify IgG with Pearl™ IgG Purification Resin. Easily purify antibodies from cell culture supernatant and ascites fluid with the Pearl™ Monoclonal IgG Purification Kit.

Also available are our proprietary, prepacked, G-Trap™ columns. The G-Trap™ Protein G column has a 6% agarose matrix covalently crosslinked to Protein G by a proprietary, highly efficient coupling chemistry. The recombinant Protein G has been designed to exclude the albumin and cell surface binding regions of the protein.  The G-Trap™ Protein G column is available in both 1mL and 5mL sizes. The G-Trap™ Protein A column is packed with fast flow resin, which is covalently coupled to recombinant Protein A. Recombinant Protein A is coupled covalently by proprietary coupling method to highly crosslinked 6% agarose. The recombinant Protein A, produced in E. coli, has been genetically engineered to enhance its binding capacity to the antibodies.

Purify IgG molecules in near neutral pH with our low cost, high binding capacity Thiophilic Adsorption Resin Kit. This kit includes all of the buffers and columns necessary for your IgG purification. For IgM purification, IgY purification, and general protein purification we recommend our Thiophilic Resin.

G-Biosciences also provide accessories for recombinant protein purification such as IgG Binding, Wash, and Elution Buffers.  For more information please download our Protein Purification and Protein Resin Handbooks.
