A new gene in A. rubens: A sea star Ig kappa gene.

The sea star Asterias rubens reacts specifically to the antigen:HRP (horse-radish peroxydase) and produces an antibody anti-HRP. We previously identified a candidate Ig kappa gene corresponding to this manuscript. We show now the gene referred to as: “sea star Ig kappa gene in its specificity”.

Immunological Properties Evidence by the A rubens Sea Star immunoglobulin Kappa Gene

In 2013-2014, we had discovered a sea star Igkappa gene, showing 2 Ig sites, after star sea immunizations to HRP. By using this gene and introducing it into an Escherichia coli plasmid, we were able to verify that this gene had the property to induce a specific immune response to the enzyme HRP (Horse- radish peroxydase).
