Tosoh Bioscience introduces Protein L resin
Protein L-based affinity chromatography is used for the capture of antibodies and fragments that do not bind to protein A. Typical protein L binding regions are antigen binding fragments, single-chain variable fragments and domain antibodies. The high binding capacity and great alkaline resistance of TO YOPEAR L AF-rProtein L-650F resin remarkably improves process economics in the production of antibody related recombinant molecules.
