    Published: 8 January 2017
    Abstract: The interactions of cefoperazone sodium with bovine transferrin and bovine serum albumin were studied by multi-spectroscopic methods. Results showed that the intrinsic fluorescence of proteins was quenched by the cefoperazone sodium with a static quenching procedure. The thermodynamics parameters indicated that electrostatic attraction played a maj... Show More
