Abstract: The present invention relates to recombinantly constructed proteins useful for analytical assays, in particular for determining in a biological sample obtained from an individual the presence of antibodies specific for a rhabdovirus. More particular, the present invention relates to a polypeptide comprising an ectodomain of a rhabdovirus glycoprotein and a heterologous multimerization domain linked to said ectodomain. In one example, a fusion protein of the formula x-y-z is provided, wherein x consists of or comprises such an ectodomain being optionally free of a furin cleavage site, y is a linker moiety, and z is a heterologous multimerization domain optionally selected from the group consisting of immunoglobulin sequence, coiled coil sequence, streptavidin sequence, fibritin sequence, and avidin sequence.

Abstract: The present invention relates to recombinantly constructed polypeptides useful for preparing vaccines, in particular for reducing one or more clinical signs caused by an infection with at least one pathogen, such as clinical signs caused by a viral infection. More particular, the present invention is directed to a polypeptide comprising a Circoviridae capsid protein linked to a heterologous protein or fragment thereof, and to chimeric virus-like particles composed of such polypeptides. In one example, a fusion protein is provided which comprises PCV2 ORF2 protein linked to an immunogenic fragment of rotavirus VP8 protein, and which is usable for reducing one or more clinical signs, mortality or fecal shedding caused by a rotavirus infection in swine.

Abstract: The present invention relates to recombinantly constructed polypeptides useful for preparing vaccines, in particular for reducing one or more clinical signs caused by a rotavirus infection. More particular, the present invention is directed to a fusion protein comprising in N- to C-terminal direction (i) an immunogenic fragment of a rotavirus VP8 protein and (ii) an immunoglobulin Fc fragment such as, for example, an IgG Fc fragment, wherein said fusion protein is usable in a method of reducing one or more clinical signs, mortality or fecal shedding caused by a rotavirus infection in swine.

Abstract: Genetically-engineered fluorophore molecules with increased fluorescence are provided. These fluorophores are derived from the domains of phytochromes, and in particular bacterial phytochromes. Methods for generating these fluorophores and various applications of these fluorophores are also provided.
