nProtein A Sepharose^™ 4 Fast Flow

nProtein A Sepharose^™ 4 Fast Flow is native protein A coupled to Sepharose^™ 4 Fast Flow for the purification of monoclonal and polyclonal antibodies at both laboratory and process scale.

nProtein A Sepharose^™ 4 Fast Flow is native protein A coupled to the well established Sepharose^™ 4 Fast Flow base matrix. The native protein A ligand is produced by fermenting a selected strain of Staphylococcus aureus. The purified protein is coupled to the cross-linked 4% agarose base matrix by the cyanogen bromide technique, giving a highly stable medium with minimal non-specific adsorption. nProtein A Sepharose^™ 4 Fast Flow is manufactured without using animal-derived components.

nProtein A Sepharose^™ 4 Fast Flow has nearly twice the total IgG binding capacity of Protein A Sepharose^™ CL-4B, and is suitable for recovery and purification of monoclonal antibodies from cell culture at both laboratory and process scale. nProtein A Sepharose^™ 4 Fast Flow was developed and tested in co-operation with leading manufacturers of purified monoclonal antibody products, and is used in routine commercial production.

As member of the BioProcess media range, nProtein A Sepharose^™ 4 Fast Flow meets industrial demands with security of supply and comprehensive technical and regulatory support.

pH below 3 is sometimes required to elute strongly bound IgG species. However, protein ligands may hydrolyze at very low pH.
