Competitive enzyme immunoassay for apolipoprotein A-II.
A competitive enzyme immunoassay for apolipoprotein A-II was developed. Microtitre plates were used as a solid phase and coated with anti-apolipoprotein A-II antibodies. Purified apolipoprotein A-II, labelled with horseradish peroxidase was used as competing ligand. The assay was examined with respect to the optimal amounts of specific anti-apolipoprotein A-II antibodies and apolipoprotein A-II...
متن کاملEnzyme immunoassay for oxytocin.
A competitive, double antibody enzyme immunoassay for oxytocin in a heterologous system was developed. Horseradish peroxidase was conjugated with oxytocin using N-succinimidyl 3-(2-pyridyldithio) propionate, and rabbit anti-oxytocin serum was produced by immunization of oxytocin-bovine serum albumin complex which was prepared by the carbodiimide method. The sensitivity of the assay was 4 microI...
متن کاملIrreversible enzyme-shuttle immunoassay.
The concept of a competitive enzyme immunoassay that utilizes simultaneously the bound and the free analyte-enzyme conjugate (heterobifunctional conjugate) for signal generation in response to varying analyte concentrations in samples has been investigated. Two antigenic sites of the heterobifunctional conjugate are used in the assay for binding to immunoglobulins: the analyte derivative binds ...
متن کاملElectrochemical enzyme-immunoassay
"Immunoassay" defines the body of techniques which use the antibody (Ab) macromolecule, usually of the IgG class, for the detection and quantitation of an enormous range of simple and complex antigen (Ag) molecules. The success of the methods relies on both the specificity and formation constant of the Ab used, and the ability to detect the interaction between Ab and Ag. Sensitive assays in com...
متن کاملEnzyme immunoassay for gentamicin.
We describe a gentamicin assay in which a peroxidase-gentamicin conjugate competes with gentamicin for binding to a gentamicin antibody adsorbed to a polystyrene solid phase. The assay can be completed in 30 min and requires 50 microliter of diluted serum. The precision and accuracy are equivalent to that of a radioimmunoassay technique and the reagents are stable for several months.
