Protein G XPure Agarose Resin consists of recombinant Protein G covalently bound to highly crosslinked agarose beads. It provides a very stable bond that can greatly minimize leakage of the Protein G allowing for reuse of the affinity resin. The XPure series of resins are made for large scale and fine purification using a high-performance liquid chromatography (HPLC) system.
