Bence-Jones Protein , Rat Igg, H.R.P , Alkaline Phosphatase, Bovine Serum Albumine used as Antigens in the Immune Response of the Sea Star

Immunocompetent cells were described in the sea star Asterina gibbosa: they recognize specifically various antigens. In the present work, Asterina gibbosa were immunized with Bence-Jones protein , other ones with Rat IGG, at last certain with H.RP ( Horse-radish Peroxydase) and the last ones with Alkaline Phosphatase: a crossed immune reaction occurs between Rat IGG and B.J protein, but not between B.J and H.R.P not between Rat IGG and H.R.P and not between Alkaline Phosphatase and B.J, not between Alkaline Phosphatase and Rat IGG, used as antigens.
