Abstract Background Studies on Rift Valley Fever Virus RVFV infection process and morphogenesis have been hampered due to the biosafety conditions required to handle this virus making alternative systems such as recombinant virus-like particles that may facilitate understanding of these processes are highly desirable. In this report we present the expression and characterization of RVFV structural proteins N Gn and Gc and demonstrate the efficient generation of RVFV viruslike particles VLPs using a baculovirus expression system. Results A recombinant baculovirus expressing nucleocapsid N protein of RVFV at high level under the control of the polyhedrin promoter was generated. Gel filtration analysis indicated that expressed N protein could form complex multimers. Further N protein complex when .
