[Immunogenic activity of hemocyanin from the hemolymph of Helix pomatia and Octopus vulgaris].

The immunogenic activity of Helix Pomatia Haemocyanin (HPH) and Octopus vulgaris Haemocyanin (OVH) has been tested in rabbits. Primary and secondary antibody response has been evaluated in sera by agar double immuno-diffusion test (Ouchterlony), counter immunoelectrophoresis and complement fixation. Bath haemocyanins proved highly antigenic: antibody titers rising up to 1/3.200 after the second antigenic challenge. The Ouchterlony test showed a partial identity between H.P.H. and O.V.H. No adverse effect was evident in injected animals.
