Recombinant Protein L is an immunoglobulin-binding protein
that originates from the bacteria Peptostreptococcus magnus.
The albumin-binding domain, cell wall and cell membrane binding domains
have been eliminated to ensure the maximum specific IgG binding capacity.
Protein L has the unique ability to bind kappa light chain
interactions without interfering with an antibody's antigen-binding site.
This gives Protein L the ability to bind a wider range of Ig
classes and subclasses than other antibody-binding proteins.
Protein L will bind to all classes of Ig (IgG, IgM, IgA, IgE and IgD).
Protein L will also bind single chain variable fragments (scFv) and Fab fragments.
Protein L binds to kappa I, III, and IV in human and kappa I on mouse.​
