摘要:
An aminocoumarin conjugated to a fluorescent label through a secondary amine, is operative as a fluorescent polarization probe of the DNA gyrase B or topoisomerase IV E subunit. The probe is used for detecting topoisomerase inhibitor binding by fluorescence polarization, particularly in a high-through put topoisomerase inhibitor assay.
