一般描述
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.
特点和优势
- Replaces Protein A Sepharose™ 4 Fast Flow, the first Cytiva Protein A medium for large-scale purification of antibodies.
- Used in routine commercial production of monoclonal antibodies
- Free from animal-derived components.
