Hepatitis B Virus Core Antigen contains the fragment of core protein immunodominant regions, amino acids: 1-186 fused to a His-tag. HBV core proteins are purified by proprietary chromatographic techniques.
Hepatitis B Virus (HBV) is a small enveloped virus that belongs to the hepadnavirus family. The human Hepatitis B Virus (HBV) has a compact genome encoding four major overlapping coding regions: the core, polymerase, surface and X. The core protein is a structural protein. It packages its own mRNA, which is also known as the pregenomic RNA, to form the core particle. The increase of the core RNA expression has been shown to increase the viral replication rate.
Immunoreactive with sera of HBV-infected individuals.
