Measurement of benzo(a)pyrene-DNA adducts by enzyme immunoassays and radioimmunoassay.
Ultrasensitive enzymatic radioimmunoassay (USERIA) was compared to radioimmunoassay and enzyme-linked immunosorbent assay in determining the amount of benzo(a)pyrene [B(a)P] metabolite covalently bound to guanine in DNA. In the USERIA approach, DNA either with or without B(a)P metabolite modification was adsorbed on the wells of microtiter plates, and rabbit antiserum to B(a)P metabolite-modifi...
متن کاملInteractions among enzyme, antibody, drug, and time in enzyme immunoassays for drugs of abuse.
Published information on the major interactive variables of enzymic immunoassays for drugs, whether in urine or serum, is scanty. Using the Syva EMIT-dau Barbiturates assay as an example, we examined the following interactive variables with respect to test response: concentrations of enzyme, antibody, and drug; urine matrix; and time. The results suggest a process for optimizing this type of en...
متن کاملPrevalence of anti-HBc in HBsAg negative blood donors using two enzyme immunoassays kits
Abstract Background and Objectives Use of kits with high sensitivity and specificity to determine the prevalence of antibodies against hepatitis B virus (anti-HBc) core antigen is important. The aim of this study was to determine the prevalence of hepatitis B virus antibody in HBsAg negative blood donors using two anti-HBc enzyme immunoassay kits (DIA.PRO and SIEMENS). Materials and Methods...
متن کاملQuantitative homogeneous enzyme immunoassays for amitriptyline, nortriptyline, imipramine, and desipramine.
We describe specific EMIT homogeneous enzyme immunoassays for amitriptyline, nortriptyline, imipramine, and desipramine in patients' serum samples. Before analysis, an easily performed extraction step involving the use of 500 microL of sample and a 1-mL disposable column eliminates cross-reacting polar metabolites. The range of the standard curve for the first three drugs is 25 to 250 microgram...
متن کاملComparison of monoclonal and polyclonal enzyme immunoassays for carcinoembryonic antigen.
A new commercially available CEA immunoassay, using monoclonal antibody, was evaluated for the purpose of routine clinical use. The between-day coefficient of variation was 5.2% at the 6.6 micrograms/l level and 4.1% at the 14.2 micrograms/l level. The results of analysis of sera from 260 patients were compared with the data from an established method with polyclonal antiserum. A good correlati...
