Protein L is a bacterial protein (from Peptostreptococcus magnus) that binds to the kappa light chains of IgG-type antibodies. However, it does not bind to lambda light chains. As such, Protein L gold conjugates allow for convenient and quick conjugation of antibodies containing a kappa chain to the gold surface, which can then be utilized further downstream. An advantage of Protein L over Protein A and Protein G is that it is capable of binding to single-chain antibody fragments (scFv) and Fab fragments, allowing for finer optimization. Abvigen Protein L conjugated gold nanoparticles are suitable for use in applications such as lateral flow, immunoblotting, light microscopy, and electron microscopy applications procedures for secondary detection of human and mouse kappa chaincontaining antibodies in labeled samples.
