Easy to use, high-binding capacity, non-adherent beads. Useful for immunoprecipitation and enrichment of antibodies. High affinity for kappa-light chain containing Ig antibodies from a variety of species. Protein L binds to all IgG subclasses from human, mouse and rat species. It also binds to human, mouse and rat IgM, IgA, IgE and IgD, as well as FAB with Kappa-light chains. Protein L is superior for binding chicken, hamster and porcine IgG.||Protein L Magnetic Beads are prepared by covalently coupling Recombinant Protein L (contains five Ig kappa light chain binding domains) to 6% cross-linked magnetically beaded agarose. The coupling technique is optimized to give a high binding capacity. The capacity of IgG binding is generally greater than 10mg of human IgG/ml of wet gel.||Applications:|Suitable for use in Immunoprecipitation and enrichment of IgG antibodies. Other applications have not been tested. ||Storage and Stability:|Store at 4°C. Stable for 12 months after receipt of the product.
