Antigen in ELISA and Western blots, excellent antigen for detection of HBV with minimal specificity problems.

The protein contains the the HBV HBe adw immunodominant region and is fused to a GST-tag.

Background: Hepatitis B virus (HBV) is a small enveloped virus that belongs to the hepadnavirus family. The genome of the hepatitis B virus (HBV), a partially doublestranded circular DNA, has four known genes encoding the viral surface proteins (pre-S 1, pre-S2 and HBsAg), the precore (pre-C) and core (C) proteins (HBeAg and HBcAg), the DNA polymerase, the X protein. The synthesis and secretion of HbeAg are linked to the expression of the pre-C region, a small open reading frame (ORF) preceding the C region initiation codon in all HBV genomes so far sequenced. In the course of HBV infection, detection of HBeAg generally correlates with active viral replication and liver disease. The presence of hepatitis B e antigen (HBeAg) in serum indicates active viral replication in hepatocytes. HBeAg is thus a surrogate marker for the presence of hepatitis B virus DNA.

Specificity: Immunoreactive with sera of HBV-infected individuals.
