Protein L-agarose is used in affinity chromatography, protein chromatography, antibody purification and characterization, immunoaffinity matrices, phosphorylation analysis, and protein A, G and L resins. Protein L-agarose has been used to provide evidence that antineuronal antibodies may contribute to neuronal dysfunction observed in a subset of patients with neurogenic chronic intestinal pseudoobstruction. Protein L agarose has also been used to evaluate a diabody to improve protection againse a potent scorpion neurotoxin.
Protein L from Peptostreptococcus magnus binds immunoglobulins (Ig) primarily through kappa light chain interactions without interfering with the antigen binding site. Recombinant Protein L contains four Ig-binding domains.
Preparation Note
Prepared with recombinant Peptostreptococcus magnus Protein L.

Pregnancy-associated malaria (PAM) is associated with the massive sequestration of erythrocytes infected with CSA-binding parasites in the placenta. Natural protective immunity against PAM is acquired during the course of pregnancies, with the development of anti-PfEMP1 antibodies recognizing placental infected erythrocytes

Diabodies are recombinant, dimeric, antibody-based molecules composed of two non-covalently associated single-chain antibody fragments that bind to an antigen in a divalent manner. In an attempt to develop more effective therapeutic molecules against scorpion venoms, we designed a diabody derived

Monoclonal antibodies (MAbs) provide a powerful tool for the identification of novel tumour associated antigens. In an attempt to identify such an antigen, MAbs were generated by immunization with paraffin wax-embedded formalin-fixed invasive ductal breast tumour tissue from a patient
This work investigated the adsorption of autoantibodies such as anti-SS-A/Ro, anti-SS-B/La, anti-Sm, and anti-dsDNA on protein L-agarose gel. In order to determine better conditions for IgG adsorption on this matrix, some buffer systems were tested. Adsorption data were analyzed using
Activation of autoimmune pathways has been implicated as a contributing mechanism to the pathophysiology in some patients with chronic intestinal pseudoobstruction (CIP). In this study we tested the hypothesis that sera from a subpopulation of patients with CIP contain autoantibodies
