Abstract
A method to express rotavirus genes in a baculovirus system. Different clones are used to express rotavirus genes for all of the viral proteins. These proteins are isolated in their native conformation. Some of these proteins show antigenic properties and are used to vaccinate human, agricultural animals and pet animals against diarrheal disease. The antigenic proteins are also used to detect the presence of the viral infectious agent either by themselves or in conjunction with antibodies produced against the antigenic proteins.
Claims8
A vaccine for rotavirus, comprising:
- a rotavirus antigen synthesized from recombinant molecules comprising a baculovirus gene promoter and at least one rotavirus gene, said promoter spatially positioned in relation to said gene effective to regulate the expression of said gene, wherein said antigen is selected from the group consisting of VP1, VP2, VP3, VP4, VP7, VP9, NS35, NS34, NS28 and any combination thereof.
A vaccine for rotavirus, comprising:
- a rotavirus antigen synthesized from recombinant molecules comprising a baculovirus gene promoter and at least one rotavirus gene, said promoter spatially positioned in relation to said gene effective to regulate the expression of said gene, wherein said antigen is a mixed antigen formed by co-expressed genes of recombinant molecules.
A vaccine for rotavirus, comprising:
- a rotavirus antigen synthesized from recombinant molecules comprising a baculovirus gene promoter and at least one rotavirus gene, said promoter spatially positioned in relation to said gene effective to regulate the expression of said gene, wherein said antigen is a mixed antigen formed by separately synthesizing an antigen selected from the group consisting of VP1, VP2, VP3, VP4, VP6, VP7, VP9, NS35, NS34, NS28 and any combination thereof, and subsequently mixing the synthesizing antigens in vitro.
