A comparative study of serum proteins ability to scavenge active oxygen species: O2-. and OCl-.
The ability of serum proteins (albumin, immunoglobulin G) and protein antioxidants (ceruloplasmin, superoxide dismutase and transferrin) to react with O2-. and OCl-, was studied. The interaction between serum proteins and OCl- was shown to be non-specific. Ceruloplasmin is the most effective OCl- trapping protein, and it reacts with O2-. with a considerable efficiency. Therefore, ceruloplasmin is supposed to be the main scavenger of toxic oxygen species generated by stimulated neutrophils.
