Phospholipase and proteolytic activities induced by cnidarian extracts. (1) C. gigantea (body-wall), (2) C. gigantea (total), 3) M. alcicornis, (4) S. helianthus (5) P. homomalla and (6) B. annulata. (a) The PLA2 activity using the indirect hemolytic assay on agarose gels containing red blood cells and egg-yolk phospholipids and by (b) Hydrolysis of the NBD-PC by cnidarian extracts (1–6). (c) Proteolytic activity upon 1% casein evaluated with 100 and 500 μg of cnidarian extracts for 30 min at 37 °C. Results are reported as mean % ± SD (n = 3)
