Evaluation of alternative counting methods for radioimmunoassay of hepatitis-associated antigen (HB-Ag).
Alternative counting methods for the Abbott “AusR1A” hepatitis-associated antigen test have been devised and evaluated. These methods involve solubilization of the tube-bound radiolabeled complex with glacial acetic acid, transfer of the eluate to a counting vial of choice, and measurement by either a gamma scintillation or a liquid scintillation system. These methods, when compared to the dire...
متن کاملEvaluation of Enzyme Linked Immunosorbent Assay, Utilizing Native Antigen B for Serodiagnosis of Human Hydatidosis
Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...
متن کاملPreparation of prostate specific antigen standards for immunoradiometric assay
Background: Immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (PSA) in clinical laboratories. Usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. Thus in order to avoid these problems the artificial matrix was used which acts sim...
متن کاملEvaluation of turkey erythrocyte hemagglutination assay for the detection of hepatitis B antigen.
A recently described hemagglutination test for hepatitis B antigen (HBsAg) using turkey erythrocytes coated with horse antibody to HBsAg purified by affinity column chromatography was evaluated on a comparative basis with 100 HBsAg-positive and -negative serum samples. The turkey erythrocyte hemagglutination test (TEHA) was found to be less sensitive than radioimmunoassay (RIA) but gave far bet...
متن کاملAustralia Antigen (a Hepatitis-associated Antigen)
Australia antigen [Au(1)], a particle associated with viral hepatitis, was isolated from the plasma of a patient with chronic anicteric hepatitis and leukemia who had received radioactive phosphorus. We have found that the immunoreactivity and appearance of Au(1) in the electron microscope were not altered by treatment with enzymes including trypsin, pronase, lipase, phospholipase C, ribonuclea...
