ELISA assay for the determination of expression levels of SODs in P. dicentrarchi trophonts exposed in vitro to ultraviolet (UV) radiation (3 J) relative to non-radiated trophonts (none). (A,B) The assay included polyclonal antibodies against the recombinant proteins of forms 2 and 3 of Cu/ZnSOD (anti-rCSD2 and anti-rCSD3, respectively), (C) Mn-SOD (anti-rMSD) and (D) Fe-SOD (anti-rFSD). The level of recognition was evaluated against the SODs present in peak 2 (P2) purified by ion exchange chromatography (see Fig. 1), using the proteins recombinants (rCSD2, rCSD3, rMSD and rFSD) as response controls and a sample of L5 culture medium to determine the presence of extracellular forms of SOD. The asterisks indicate statistically significant differences (P < 0.01), relative to the non-irradiated controls (determined by Student t test).
