Title
(EN) MODIFIED S1 SUBUNIT OF THE CORONAVIRUS SPIKE PROTEIN
(FR) SOUS-UNITÉ S1 MODIFIÉE DE LA PROTÉINE DE SPICULE DE CORONAVIRUS
Abstract
(EN)
The present invention relates i.a. to a recombinant avian coronavirus spike protein or fragment thereof comprising a mutation at amino acid position 267 to Cysteine. Further, the present invention relates to an immunogenic composition comprising an avian coronavirus with such spike protein.
(FR)
La présente invention concerne entre autres une protéine de spicule de coronavirus aviaire recombinant ou un fragment de celle-ci comprenant une mutation au niveau de la position d'acide aminé 267 en cystéine. En outre, la présente invention concerne une composition immunogène comprenant un coronavirus aviaire avec une telle protéine de spicule.
