Abstract
The invention relates to the expression of open reading frame 2 (ORF-2) proteins of a strain of hepatitis E virus from Pakistan (SAR-55) in a eukaryotic expression system. The expressed proteins can serve as an antigen in diagnostic immunoassays and/or as an immunogen or vaccine to protect against infection by hepatitis E.
