Abstract:
The binding characteristics of quinolone antibacterial agent, ofloxacin (OFLX) and ciprofloxacin(CPFX) with catalase(CAT) were studied by fluorescence spectroscopy in aqueous solution. It was showed that both OFLX and CPFX had a strong ability to quench the CAT intrinsic fluorescence through a static quenching procedure. The formation constant K and the number of bind ing site n were further calculated according to the fluorescence quenching r esults.
