    Activation of a Refolded, Berberine-specific, Single-chain Fv Fragment by Addition of Free Berberine

    A single-chain variable fragment (scFv) specific for berberine was produced in Escherichia coli. The anti-berberine scFv gene was cloned from hybridoma 1D5-3B-7 producing the monoclonal antibody. The variable reg...
