HEV-ORF2/ORF3/2 Mosaic protein.The protein is a mosaic of 12 immunodominant HEVORF2-ORF3 fragments.Hepatitis E Virus protein is purified by proprietarychromatographic techniques.Hepatitis E virus (HEV) is a major human pathogen inmuch of the developing world. It is a plus-strand RNAvirus with a 7.2-kb polyadenylated genome consisting ofthree open reading frames, ORF1, ORF2, and ORF3. Ofthese, ORF2 encodes the major capsid protein of the virusand ORF3 encodes a small protein of unknown function. Purity >95% by SDS-PAGE and RP-HPLC
