Popis: A problem faced in proteomics studies is the recovery of tagged protein complexes in their native and active form. Here we describe a peptide, Bio-Ox, that mimics the immunoglobulin G (IgG) binding interface of Staphylococcus aureus Protein A, and competitively displaces affinity-purified Protein A fusion proteins and protein complexes from IgG-Sepharose. We show that Bio-Ox elution is a robust method for the efficient and rapid recovery of native tagged proteins, and can be applied to a variety of structural genomics and proteomics studies.
