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.

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.

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 ...

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 ...

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.

Donors With Hepatitis B Surface Antigen Positivity
Transplantation Proceedings, 2015There is a still controversy among transplantation centers regarding acceptance of hepatitis B surface antigen (HBsAg)-positive donors for renal transplantation. However, some reports show that these donors can be used under a special protocol. In this study, we compared the clinical and biochemical parameters of patients who received kidneys from ...
