Recombinant HAV-VP3 may be used in ELISA and Western blots, excellent for detection of HAV with minimal specificity problems.

The protein contains the HAV VP3 immunodominant regions, amino acids: 304-415. Hepatitis A Virus VP1 protein is purified by proprietary chromatographic techniques.

Background: HAV, the prototype of the genus Hepatovirus, belongs to the family Picornaviridae. Its 7.5-kb single-stranded RNA genome bears different distinct regions: the 5' and 3' noncoding regions (NCR), the P1 region, which encodes the structural proteins VP1, VP2, VP3, and a putative VP4, and the P2 and P3 regions encoding nonstructural proteins associated with replication. Hepatitis A virus (HAV) encodes a single polyprotein which is posttranslationally processed into the functional structural and nonstructural proteins. Only one protease, viral protease 3C, has been implicated in the nine protein scissions.

Specificity: Immunoreactive with sera of HAV-infected individuals.
