HEV-ORF2 (residues 403-461) protein.The protein is fused with beta-galactosidase at theN-terminus and contains immunodominant HEV ORF2fragment, amino acids: 403-461.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
