rProtein L Beads 4FF is an affinity chromatography medium designed for purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. The recombinant protein L ligand is immobilized to highly cross-linked 4% agarose beads. The Characteristics of rProtein L Beads 4FF are summarized in Table.
Protein L is recombinantly expressed in E. coli and retains the property of binding to the antibody κ-chain without affecting the antigenic binding site of the antibody. Protein L binds well to the kappa light chain of human and mouse, and may bind specifically to certain kappa isoforms of other species. Protein L binds weakly to rabbit immunoglobulins and does not bind bovine, goat or sheep source immunoglobulins.
