An enzyme-linked immunosorbent assay (ELISA) was developed which permits the assay of
specific secretory immunoglobulin A (sIgA) antibodies against hepatitis B surface antigen …

Saliva is rapidly being recognized as an increasingly important diagnostic medium. It is a
complex mixture of fluid arising from the major salivary glands, the minor (accessory) …

Because the various forms of viral hepatitis are often spread by persons with inapparent
infection, screening of patient contacts is a primary preventive strategy. Although a number …

Two hundred and twelve saliva specimens of HB s Ag carriers were tested for HB s Ag by
crossover immunoelectrophoresis (CIEP) and radioimmunoassay (RIA) after concentration …

Abstract The distribution of IgG, IgA, IgM and IgD was assessed in concentrates of parotid
saliva, gastric juice and duodenal contents from 49 human subjects. Immunoglobulin A …

Hepatitis B., surface antigen (HBsAg) was detected by solid phase radioimmunoassay (RIA)
in mixed saliva of 15 out of 50 antigenemic patients. The salivary antigen was present in low …

We have produced a monoclonal antibody (MAb), designated 11G12, of IgG1 isotype that
recognizes group-specific epitopes of the HBsAg. It was demonstrated that the same MAb …

Hepatitis B surface antigen (HB s Ag) was isolated from human serum by two steps of affinity
chromatography on antibody-coated gels. HB s Ag-positive serum was passed through a …

Hepatitis B surface antigen (HB s Ag) was detected in whole saliva and in gingival crevicular
fluid of 28 (90 per cent) of 31 seropositive patients. No correlation was found between the …

Background: Saliva is increasingly being investigated as an alternative to serum for
diagnostic and epidemiological testing even though antibody levels are substantially lower …
