rProtein A (4xZ)

  • Protein A is an immunoglobulin-binding cell wall protein naturally produced by Staphylococcus aureus and widely used as a generic ligand for the purification of monoclonal and recombinant antibodies.

    Biomedal’s rProtein A (4xZ) is a synthetic derivative of the native protein A molecule, produced by recombinant expression in E. coli and purified using a highly efficient, immunoglobulin-free process. rProtein A (4xZ) contains four identical copies of an Fc region-binding domain assembled in a single 29.88 kDa polypeptide, and can be coupled to solid supports to produce affinity media suitable for antibody capture and elution under standard conditions.

    Applications:

    • Antibody purification
    • Immunoprecipitation of proteins and protein complexes.
    • Antibody detection in Western blot, ELISA, etc.
