Solid-phase enzyme immunoassay for hepatitis B surface antigen.
A solid-phase enzyme immunoassay is described for measuring hepatitis B surface antigen in human serum or plasma. Immunologically purified antibody labeled with horseradish peroxidase was used as the indicator. In the assay system, antibody-coated controlled-pore glass is used as a solid support and there are three sequential incubations, totaling 2 h, at room temperature. Results for serially...
متن کاملSolid-phase enzyme-immunoassay for detection of hepatitis B surface antigen.
The preliminary results of a solid-phase enzyme-immunoassay (EIA) for the detection of hepatitis B surface antigen (HBsAg) are presented. This method has been compared with the solid-phase radioimmunoassay (RIA) for HBsAg in dilution series of four HBsAg positive sera four national reference panels (The Laboratory Panel of the Central Laboratory of the Blood Transfusion Service of the Netherlan...
متن کاملDetection of human antibodies to hepatitis B surface antigen (HBsAg) by an enzyme-immunoassay for HBsAg.
We studied the feasibility of detecting antibody to hepatitis B surface antigen (anti-HBs) by an inhibition assay using the reagents of an enzyme-immunoassay for HBsAg (Hepanostika). Several modifications of the basic assay were investigated. Sensitivity was greatest when the test sample was incubated with a predetermined amount of HBsAg before the usual procedure of HBsAg detection. The presen...
متن کاملSolid-phase enzyme immunoassay for serum ferritin.
We describe a solid-phase enzyme immunoassay for ferritin in human serum, with use of a horseradish peroxidase-labeled antibody and a highly sensitive chromogen, 2,2'-azino-di(3-ethyl-benzthiazoline-6-sulfonate). The assay requires only 10 microL of serum per assay, relatively less time and labor than other assys for ferritin, and as little as 10 pg of ferritin can be measured. We believe this ...
متن کاملFalse-positive results with third-generation monoclonal hepatitis B surface antigen enzyme immunoassay.
Nonspecific hepatitis B surface antigen reactions with a third-generation enzyme immunoassay (Auszyme Monoclonal; Abbott Laboratories, North Chicago, Ill.) were investigated with 9,577 serum specimens in a clinical laboratory setting. Of the 196 serum specimens found reactive in Auszyme screen by the overnight procedure, 103 turned out to be true-positives, 71 were nonrepeatably reactive, and 2...
