Immunoassay for Human Chorionic Gonadotropin Based on Glassy Carbon Electrode Modified with an Epitaxial Nanocomposite
A highly sensitive electrochemicalimmunosensor was developed to detect hCG based on immobilization ofhCG-antibody (anti-hCG) onto robust nanocomposite containing Gr, Chit,1-methyl-3-octyl imidazolium tetra fluoro borate ionic liquid (IL)(Gr-IL-Chit). AuNPs were used to immobilize hCG antibody on the modifiedelectrode. The amine groups of the antibody are cova...
متن کاملImmunoassay of human chorionic gonadotropin, its free subunits, and metabolites.
Multiple hCG-related molecules are present in pregnancy serum and urine samples. These include non-nicked hCG (the hormone), nicked hCG, hyper- and hypoglycosylated hCG, hCG missing the C-terminal extension, free alpha-subunit, large free alpha-subunit, free beta-subunit, nicked free beta-subunit, and beta-core fragment. Over 100 immunoassays are sold for quantifying hCG-related molecules in se...
متن کاملHuman Chorionic Gonadotropin
A highly active preparation of human chorionic gonadotropin has been obtained by simple methods of column chromatography on diethylaminoethyl Sephadex and Sephadex G-100. The preparation appeared homogeneous by disc and immunoelectrophoresis, ultracentrifugation, and end group analysis. It assayed at 12,000 i.u. per mg by the rat prostrate gland and accessory sex organ method. The ~20,~ value w...

متن کاملCompetitive enzyme immunoassay for diagnosis of human brucellosis.
The methods commonly used for human brucellosis serological testing are agglutination tests and the complement fixation test (CFT). Among the newer serological tests, primary binding assays were developed to improve sensitivity and specificity. The competitive enzyme immunoassay (CELISA) for the detection of serum antibody to Brucella is a multispecies assay which appears to be capable of diffe...
