Evaluation 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 کاملdevelopment of a sensitive enzyme-linked immunosorbent assay for detection of hepatitis b surface antigen using novel monoclonal antibodies
hepatitis b virus (hbv) infection is the 10th leading cause of death worldwide. the most important diagnostic and screening marker for hbv infection is hepatitis b surface antigen (hbsag), and the most widely used hbsag screening test is enzyme-linked immunosorbent assay (elisa). in this study, an elisa assay has been developed for detection of hbsag using two novel monoclonal antibodies (mab) ...
متن کاملAn enzyme-linked immunosorbent-assay test for hepatitis B surface antigen.
A new commercial test for hepatis B surface antigen based on an enzyme-linked immunosorbent-assay system was evaluated and compared with other tests already available. It was of comparable sensitivity to the radioimmunoassay test but required less expensive equipment (in terms of both outlay and upkeep) and did not use radioisotopes; the reagents were more stable.
متن کاملStandardization of an Enzyme-Linked Immunosorbent Assay for Detection of Infectious Bronchitis Virus Antibody.
An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...
متن کاملEnzyme-linked immunosorbent assay for detection of Streptococcus pneumoniae antigen.
An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of Streptococcus pneumoniae polysaccharide antigen in cerebrospinal fluid and serum. Sensitivity and specificity were determined for purified antigen preparations. Specificity was also evaluated in the rabbit meningitis model, and the sensitivity was compared to counterimmunoelectrophoresis, using the infected rabbits'...
