Description
Protein L is a multi-domain protein found on the surface of Peptostreptococcus magnus, also known as Peptostreptococcus magnus Protein L (PPL) . Unlike Protein A or Protein G, Protein L primarily binds to the kappa light chain of antibodies without interfering with the antigen-binding domain. This unique binding mechanism enables Protein L to interact with a broader range of antibody classes and subtypes, including human IgG, IgM, IgA, and IgD containing kappa light chains, as well as mouse IgG, IgM, rat IgG, Fab fragments, and single-chain variable fragments (scFv), among others.
Product Name Alternative
Protein L, Peptostreptococcus magnus Protein L, PPL
Expression System

Nature
Recombinant
Applications
Detection and purification of antibodies and antibody fragments (Fab, ScFv) that contain kappa light chains but not the Fc region.
