Abstract
Antigens are produced by self-assembly of polypeptide components. The production of bluetongue virus antigens (BTV) in the form of assembled particles comprising separate polypeptide components, particularly proteins VP2, VP3, VP5 and VP7 is described.
Claims4
A process for preparing a Bluetongue Virus (BTV) capsid particle consisting of BTV VP3 and BTV VP7 comprising:
- (a) transforming a S. frugiperda cell with one or more vectors that mediate expression of BTV VP3 and the BTV VP7 proteins;
- (b) expressing said BTV VP3 and BTV VP7 proteins;
- and
- (c) isolating said capsid particle consisting of BTV VP3 and BTV VP7.
