Hepatitis B surface antigen in spinal fluid
Medical and Pediatric Oncology, 1980AbstractHepatitis B surface antigen (HBsAg) was detected in the cerebrospinal fluid (CSF) of five of nine leukemia patients with HBsAg‐positive sera. These five CSF samples were shown to be free of occult blood using a sensitive hemoglobin extraction technique.

Antibodies to Hepatitis B Surface Antigen
Annals of Internal Medicine, 1985Excerpt To the editor: The article by Kessler and colleagues (1) is of general interest because it shows, once again, that antibodies to hepatitis B surface antigen (anti-HBs), at least as they are...

Thyroxine Binding by Hepatitis B Surface Antigen
Journal of Infectious Diseases, 1975Thyroxine and triiodothyronine binding sites are present on the 20-nm spherical particles associated with hepatitis B surface antigen (HBsAg). Thyroxine-treated HBsAg has a buoyant density of 1.26 g/cm-3 in CsCl and appears under the electron microscope as a hexagonal particle with a center-to-vertex distance of 10 nm.

The Detection of Hepatitis B Surface Antigen by Radioimmunoassay
Pathology, 1975A comparative study was performed to assess the sensitivity and specificity of counterimmunoelectrophoresis (CIEP) and radioimmunoassay (RIA) for the detection of hepatitis B surface antigen. The 8,823 sera examined included selected reference panels and sera collected from populations with low, moderate and high rates of chronic antigen carriage ...

Thermal Inactivation of Hepatitis B Surface Antigen
The Journal of Immunology, 1978Abstract Thermal inactivation of hepatitis B surface antigen (HBs Ag) was investigated under various experimental conditions by means of a quantitative radioimmunoassay. No decrease of HBs Ag immunologic reactivity could be detected at -80°C, up to 24 months of storage, whereas at -20 and 4°C survival of serum HBs Ag after 6 months was ...

Hepatitis B Surface Antigen (HBsAg) [PDF]
, 1985 The observations (a) that antibody directed against surface antigen (anti-HBs) becomes most prevalent following recovery from acute type B hepatitis; (b) that it is often present in asymptomatic carriers without detectable HBsAg and (c) that anti-HBs may persist for many years after initial exposure to HBV suggest that anti-HBs containing serum ...

The incidence of hepatitis B surface antigen in Nigeria
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1979We have determined the incidence of hepatitis B surface antigen (HBsAg) in an urban (Enugu) and a rural (Okpatu) population groups in Nigeria. There were no statistically significant differences between the incidence in the two populations. Contrary to earlier reports we did not observe any significant age-related differences in the incidence rates ...

Subtyping of hepatitis B surface antigen by radioimmunoassay
Journal of Immunological Methods, 1979Abstract A solid-phase radioimmunoassay used for HBsAg screening of blood donors at the Finnish Red Cross Blood Transfusion Service (FRC-RIA) was modified for subtyping of HBsAg. The anti-HBs coated test tubes of FRC-RIA served as the solid-phase anti-HBs.

Concomitant Hepatitis B Surface Antigen and Antibody
Annals of Internal Medicine, 1984Excerpt To the editor: Recently, Foutch and associates (1) reported the presence of hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs) in 13 patients.
