Protein A Resin
Protein A resin is a chromatography medium functionalized with Staphylococcus aureus Protein A, which binds with high affinity to the Fc region of IgG antibodies from human, rabbit, and mouse sources.
Applications:
Purification of monoclonal and polyclonal IgG antibodies
Immunoprecipitation and antibody pull-down assays
Antibody-based protein complex isolation
High-specificity capture of Fc-tagged proteins
Protein L Resin
Protein L resin utilizes Protein L from Peptostreptococcus magnus, which binds to the Îş light chains of antibodies without requiring Fc binding. It is ideal for capturing antibodies that do not bind to Protein A or G.
Applications:
Purification of antibody fragments (e.g., Fab, scFv)
Capture of Ig classes with Îş light chains (e.g., mouse IgG1, human IgM, IgA)
Antibody engineering and phage display workflows
Enrichment of Îş light chain-containing antibody libraries
Protein G Resin
Protein G resin contains recombinant Protein G from Streptococcus sp., with broad affinity for a wide range of IgG subclasses across several species, including mouse, human, and rat.
Applications:
Broad-spectrum IgG purification and enrichment
Antibody-based immunoprecipitation workflows
Fc-fusion protein isolation
Antibody characterization and screening assays
Protein A/G Resin
Protein A/G resin combines the binding profiles of both Protein A and Protein G, providing a versatile platform for purifying a wide range of IgG subclasses from multiple species.
Applications:
Pan-IgG purification across diverse species
Capture of mixed antibody populations in hybridoma or serum samples
Flexible tool for antibody development and screening
Multipurpose immunoassays requiring broad binding specificity
Streptavidin Resin
Streptavidin resin is functionalized with immobilized recombinant streptavidin, offering strong, specific, and reversible binding to biotinylated molecules with minimal nonspecific interaction.
Applications:
Capture and purification of biotinylated proteins, peptides, or nucleic acids
Pull-down assays and protein interaction studies
Enrichment of biotin-tagged antibodies or ligands
Immobilization of biotinylated probes in assay development
