Serum samples containing hepatitis B e antigen (HBeAg) were subjected to electrophoresis in agarose, and fast-migrating 'small' HBeAg and slow-migrating 'large' IgG-associated HBeAg were pooled separately. HBeAg of each category was determined by a two-site radioimmunoassay that sandwiched HBeAg between monoclonal antibody (anti-HBe) against one epitope of HBeAg, fixed on a solid support, and anti-HBe against another epitope, labelled with radioiodine. Eighteen sera in which small HBeAg dominated revealed activities of hepatitis B surface antigen-associated DNA polymerase significantly higher than 14 sera in which large HBeAg dominated (logarithm of ct/min, mean +/- s.e. 3.36 +/- 0.08 versus 2.14 +/- 0.11, P less than 0.01). Shift from small HBeAg to large HBeAg was observed, along with the disappearance of DNA polymerase, in the serum from two carriers who seroconverted to anti-HBe.

UI MeSH Term Description Entries
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D002353 Carrier State The condition of harboring an infective organism without manifesting symptoms of infection. The organism must be readily transmissible to another susceptible host.

D004259 DNA-Directed DNA Polymerase DNA-dependent DNA polymerases found in bacteria, animal and plant cells. During the replication process, these enzymes catalyze the addition of deoxyribonucleotide residues to the end of a DNA strand in the presence of DNA as template-primer. They also possess exonuclease activity and therefore function in DNA repair.

D006509 Hepatitis B INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact. Hepatitis B Virus Infection
D006511 Hepatitis B Antigens Antigens of the virion of the HEPATITIS B VIRUS or the Dane particle, its surface (HEPATITIS B SURFACE ANTIGENS), core (HEPATITIS B CORE ANTIGENS), and other associated antigens, including the HEPATITIS B E ANTIGENS.

D006513 Hepatitis B e Antigens A closely related group of antigens found in the plasma only during the infective phase of hepatitis B or in virulent chronic hepatitis B, probably indicating active virus replication; there are three subtypes which may exist in a complex with immunoglobulins G.
