G-Trap™ Protein G, 1 ml, 2 Columns, 786-1036, G-BIOSCIENCES (CAT#: STEM-C-3261-LGZ)

G-trap™ Protein G is pre-packaged and ready-to-use column format for affinity purification of IgG. The columnar structure is filled with a resin that is covalently coupled to recombinant protein G.

Recombinant protein G is covalently coupled to highly cross-linked 6% agarose via a proprietary conjugation method. The employed coupling chemistry has a high coupling efficiency and a low protein G leaching rate, and thus a high binding efficiency. Recombinant protein G produced in E. coli has been engineered to genetically remove the albumin and cell surface binding regions of the protein.

G-Trap™ rProtein A FF, 1 ml and G-Trap™ rProtein A FF, 5 ml can also be used for affinity purification of immunoglobulins.
