The serum ferroxidase activity rate at 37[degrees]C was linear with respect to duration of an incubation period of 0-12 min.
The corresponding ferroxidase activity for 1 [micro]mol/L ferrous ion oxidation was calculated:
0 [micro]mol/L, the corresponding ferroxidase activity is 40 U/L.
Sodium azide completely inhibited ferroxidase activity of commercial ceruloplasmin samples; it inhibited 95-99% of serum ferroxidase activity.
The detection limit, defined as the mean ferroxidase activity of the zero calibrator + 3 SD, was 25.
Serum ferroxidase activity was not affected by storage at 4[degrees]C for 1 week and at -20[degrees]C for 1 month.
RELATIONSHIP BETWEEN FERROXIDASE AND PPD OXIDASE ACTIVITIES OF CERULOPLASMIN
The ferroxidase activity of the same ceruloplasmin samples was measured by automated analyzer.
CORRELATION BETWEEN SERUM FERROXIDASE ACTIVITY AND COPPER CONCENTRATION
Serum ferroxidase activity was determined by automated analyzer, and serum copper concentration was determined by atomic absorption spectrophotometer.
The serum ferroxidase activity and copper concentration in healthy persons and patients with Wilson disease, malaria, and bronchial asthma are shown in Table 2.
An important difficulty in various ferroxidase activity measurement methods is to prevent autooxidation of the substrate.
