ABSTRACT
Blood and seminal plasma of brown trout Salmo trutta fario were analyzed for their iron binding potential adopting two different methods. Seminal plasma showed an iron binding capacity that was retained even if samples were exposed at acid pH, similarly to mammalian lactoferrin that binds ferric iron also at acid pH. This suggests that the iron binding capacity is determined by a factor having a lactoferrin-like activity. Moreover, trout seminal plasma proteins were also analyzed in their pattern by sodium dodecyl sulphate polyacrylamide gel elecrophoresis (SDS-PAGE) and electroblotted onto nitrocellulose membrane. When seminal plasma was subjected to immunoblotting using goat anti-bovine lactoferrin antibodies as a probe, only a single band having an apparent molecular weight of around 80 kDa was specifically detected, showing that this protein has homology with bovine lactoferrin.
