    ABSTRACT: This is a report on the development of immunoaffinity chromatography using a column of silica gel with an immobilized single-chain variable fragment (scFv) antibody specific to bisphenol A (BPA) for cleanup of BPA-contaminated water samples. The BBA-2187 scFv antibody specific to BPA was purified from the periplasmic fractions of the recombinant Escherichia coli. After a sample of BPA-contaminated river water was applied to the immunoaffinity column, the background signal intensity observed in high-performance liquid chromatography (HPLC) analysis of the eluates was markedly lower than that observed in HPLC analysis of the eluates from an Oasis HLB cartridge treated with the same sample. The immunoaffinity column efficiently concentrated BPA from actual river water samples with different matrices. Our results demonstrate that the immunoaffinity column with immobilized BBA-2187 scFv antibody is efficient for the cleanup of BPA-contaminated water samples from different sources.
