The blue protein in human blood is ceruloplasmin, a member of the
larger class of enzymes called blue copper oxidases. Ceruloplasmin is
around 100 kD, as I recall, so the three bands you see may be degradation
products. The other well-studied blue copper oxidases are ascorbate oxidases
from plants and laccases from wood-rotting fungi.
