Figure 4From: Biochemical characterization and evaluation of cytotoxicity of antistaphylococcal chimeric protein P128Effect of hyper-immune sera on P128 activity. P128 was exposed at varying concentrations to hyper-immune serum and tested for biological activity against 108 cells of MRSA USA300 in the continued presence of the serum. The experiment was performed twice. Results are expressed as mean residual CFU/ml±standard deviation.Back to article page
