Hepatitis E Virus, ORF2, aa403-461, Recombinant (HEV)

Hepatitis E virus (HEV) is a major human pathogen in much of the developing world. It is a plus-strand RNA virus with a 7.2kb 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.\n\nThe protein contains immunodominant HEV ORF2 fragment, amino acids: (403-461).\n\nSpecificity:\nImmunoreactive with sera of HEV-infected individuals\n\nApplications:\nRecombinant HEV Antigen may be used in ELISA and Western Blot, excellent for detection of HEV with minimal specificity problems.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
