Hepatitis B subtypes ad and ay

Specificity

This product is specific for Hepatitis B surface antigen, recognizing subtypes ad and ay. Hepatitis B virus is a major causative agent of acute and chronic liver disease in humans. Hepatitis B surface antigen (HBsAg) is a protein component of the viral envelope, which is expressed predominantly in the cytoplasm of infected hepatocytes.

Scientific Data Images for HBsAg Antibody

Western Blot: HBsAg Antibody [NB100-62652]

Western Blot: HBsAg Antibody [NB100-62652]

Western Blot: HBsAg Antibody [NB100-62652] - HepAD38 cells were treated with DFMO (50 uM, 100 uM), and the HBV core-associated DNA was extracted 3 days later and measured by Southern blot (upper panel). The levels of HBc and HBs were measured by Western blotting, and capsids levels were determined using a Native gel assay (lower panel).

Western Blot: HBsAg Antibody [NB100-62652] -

Western Blot: HBsAg Antibody [NB100-62652] - DFMO decreases the HBV core-associated DNA & the HBc protein levels. (A) Determination of cytotoxicity of HepAD38 & HepG2.2.15 cells treated DFMO measured by the MTS assay. (B) HepAD38 cells were treated with DFMO (50 μM, 100 μM), & the HBV core-associated DNA was extracted 3 days later & measured by Southern blot (upper panel). The levels of HBc & HBs were measured by Western blotting, & capsids levels were determined using a Native gel assay (lower panel) as described above. (C) The levels of HBsAg in supernatant were measured by ELISA assay as described above. (D) HBV 3.5kb RNA levels were measured by real-time RT-PCR. (E) & (F) HepG2.2.15 cells treated with DFMO (50, 100 μM) for 3 days, then the levels of intracellular HBV DNA or HBsAg levels in the supernatant were detected by real-time PCR (E) or ELISA assay (F). (G) DFMO decreased the infection capacity of the HBV particles. HepAD38 cells in the absence of tetracycline were treated with DSMO or DFMO with indicated concentration for 3 days, & the HBV viral particles were then collected & added to the HepG2-NTCP cells. Five days later, the cytoplasmic viral DNA were extracted & measured by real-time PCR. RC, relaxed circular; DL, double stranded linear; SS, single stranded. Experiments were performed in triplicate, & data are represented as means ± SD. Statistical significance was determined by one-way ANOVA with the Tukey post-hoc test (*p < 0.05; ns, not significant).

Background: HBsAg

Hepatitis B Virus (HBV) infection induces a disease state characterised by liver damage, inflammation and viral persistence. Infection also increases the risk of hepatocellular carcinoma. HBV belongs to the Hepadnaviridae family of viruses. Its genome consists of partially double stranded circular DNA. The DNA is enclosed in a nucleocapsid, or core antigen (HBcAg), which is surrounded by a spherical envelope (surface antigen or HBsAg). The core antigen shares its sequences with the e antigen (HBeAg) but no cross reactivity between the two proteins has been observed. The HBV genome also encodes a DNA polymerase that also acts as a reverse transcriptase. Hepatitis B infection is normally diagnosed from serological tests that detect HBsAg but as the disease progresses this antigen may no longer be present in the blood and tests for HBcAg are used. If HBsAg can be detected in the blood for longer than six months, chronic hepatitis B is diagnosed. The antigenic determinant of the protein moiety of the HBsAg determines specific characteristics of different serotypes and provides the basis of immunodetection. HBsAg has antigenic heterogeneity, specifically, two pairs of sub specific determinants, d/y and w/r allow the following combinations: adw, ayw, adr, ayr.
