<p>The recombinant fusion proteins comprise the nucleocapside proteins of the porcine reproductive and respiratory syndrome virus (PRRSV), which has been obtained both from a European isolate of PRRSV and from an American isolate, and which was fused to an amino-acid sequence derived from the system selected for the expression of said recombinant fusion protein either directly or through a union region formed by a small number of amino-acids. Said recombinant fusion proteins are appropriate to be used in diagnosing PRRSV.</p> |
