Hepatitis B Virus Core Antigen (HBcAg)

HEPATITIS B VIRUS CORE ANTIGEN

Recombinantly created Hepatitis B Virus center antigen (HBcAg). This center protein section addresses part of the irresistible virions internal center molecule, which encases the viral genome.

Item DETAILS – HEPATITIS B VIRUS CORE ANTIGEN

Recombinant Hepatitis B infection Core protein created in E. coli.
Contains HBV Core immunodominant district.
Accessible in fluid arrangement and cushioned in 10 mM Tris-HCl, pH 8.0, 50 mM NaCl, 1 mM EDTA, half glycerol.
More prominent than 90% virtue by SDS-PAGE.
Immunoreactive with serum of HBV tainted people.

Foundation
HBV is a wrapped DNA infection with a 3.2-kb covalently shut roundabout DNA, which imitates inside the core of contaminated hepatocytes (Seeger and Mason, 2015). Profoundly, polymerase (P), envelope (pre-S1/pre-S2/S) and X. The pre-center/center quality is answerable for articulation of center protein as well as hepatitis B e antigen (HBeAg), a serological marker of HBV contamination corresponding with high popular burden.

The 5′ finish of pre-S1, pre-S2 and S districts all have autonomous beginning codons which can each produce three co-terminal envelope proteins called enormous (L; pre-S1 pre-S2 S), center (M; pre-S2 S), and little (S; with S area alone) envelope proteins. The S protein is the most plentiful envelope protein communicated and can be discharged freely of L and M envelope proteins. After emission, mature HBeAg is erased at buildup 149 C-terminally and holds 10 pre-center deposits N-terminally. Both L and S envelope proteins are required for virion emission, while M protein is nonessential (Bruss and Ganem, 1991; Ueda et al., 1991).

Center particles with mature (twofold abandoned DNA) genome can be encompassed and delivered as 42-nm virions, with the three envelope proteins embedded on a superficial level. Void viral particles (22-nm) are additionally bounteously delivered (Bruss and Ganem, 1991; Ganem and Prince, 2004; Zhang and Tang, 2017). HBcAg is one of the three significant clinical antigens of hepatitis B infection yet vanishes from the get-go throughout disease. It is an exceptionally immunogenic subviral molecule including 180 or 240 duplicates of the center protein and capacities as both a T-cell-reliant and a T-cell-free antigen.
