Abstract

The sea star Asterias rubens reacts specifically to the antigen: Horse-Radish Peroxydase (HRP) and produces an «antibody» anti-HRP.We had presented a candidate IgKappa gene corresponding to this last one in 2013. We show now the gene called: «sea star IgKappa gene» in its specificity. We have to know, at the present time that, at our knowledge, the sea st ar doesn’t react specifically to all the antigens.

Summary

INTRODUCTION

A first experiment which was fundamental, described in 1973, the immune response to various antigens of an asterid: Asterina gibbosa. It indicated (Leclerc, 1973), more exactly, the specific immunocytochemical response to Horse-Radish Peroxydase (HRP) of the sea star. The PCR products showed, in agarose gel, no band for the negative control and one band (400bp) for the specific PCR. This last was purified and sequenced on Illumina’s GSII platform sequencing.
