- Purification of monoclonal and polyclonal antibodies.
Sepharose is a registered trademark of GE Healthcare
Protein L Sepharose® is prepared by covalently coupling recombinant Protein L (which contains five Ig light chain binding domains) to 6% cross-linked Sepharose® beads. The coupling technique is optimized to give high binding capacity. The capacity of IgG binding is generally greater than 10 mg of human IgG per mL of wet gel. Protein L binds to a wider range of antibody classes than Protein A or Protein G, including human, mouse and rat IgM, IgA, IgE, and IgD, as well as Fab and single chain variable fragments (scFv). Protein L binds only binds to antibodies that contain Κ light chains, which are found in most human and mouse antibodies.
