Antigen in ELISA and Western blots, excellent antigen for detection of HEV with minimal specificity problems.
The protein is fused with beta-galactosidase at the N-terminus and contains immunodominant HEV ORF2 fragment, amino acids: 403-461. Hepatitis E Virus protein is purified by proprietary chromatographic techniques.
Background: Hepatitis E virus (HEV) is a major human pathogen in much of the developing world. It is a plus-strand RNA virus with a 7.2-kb polyadenylated genome consisting of three open reading frames, ORF1, ORF2, and ORF3. Of these, ORF2 encodes the major capsid protein of the virus and ORF3 encodes a small protein of unknown function.
Specificity: Immunoreactive with sera of HEV-infected individuals.
