A competitive enzyme immunoassay for the quantitative detection of cocaine from banknotes and latent fingermarks.
A sensitive and versatile competitive enzyme immunoassay (cEIA) has been developed for the quantitative detection of cocaine in complex forensic samples. Polyclonal anti-cocaine antibody was purified from serum and deposited onto microtiter plates. The concentration of the cocaine antibody adsorbed onto the plates, and the dilution of the cocaine-HRP hapten were both studied to achieve an optim...
متن کاملImmunoassay for detection of cocaine/metabolites in oral fluids.
There is growing interest in the use of alternate biological fluids for drug testing. An advantage of oral fluids is that collection can be made from individuals under direct observation without undue embarrassment or invasion of privacy. This study evaluated the STC Cocaine Metabolite MICRO-PLATE EIA for use in detection of cocaine and metabolites in oral fluids. Intra- and interassay precisio...
متن کاملValidation of an enzyme immunoassay for detection and semiquantification of cannabinoids in oral fluid.
BACKGROUND Oral fluid (OF) is gaining prominence as an alternative matrix for monitoring drugs of abuse in the workplace, criminal justice, and driving under the influence of drugs programs. It is important to characterize assay performance and limitations of screening techniques for Delta(9)-tetrahydrocannabinol (THC) in OF. METHODS We collected OF specimens by use of the Quantisal OF collec...
متن کاملEnzyme Immunoassay Detection of Nitrosomonas europaea.
An exploratory effort to selectively detect the presence of a nitrifying bacterium, Nitrosomonas europaea, successfully demonstrated the fundamental utility of an enzyme-based immunoassay protocol. The applied polyclonal antibody test seemingly offered a marked improvement over the available analytical options, including plating, activity, and fluorescence immunoassay techniques. Following an i...
متن کاملEnzyme immunoassay for aflatoxin B1-lysine adduct and its validation.
A simple procedure was developed for in vitro synthesis and characterization of aflatoxin B1-lysine adduct using aflatoxin B1, N-alpha-acetyl lysine and m-chloroperbenzoic acid (MCPBA). At a molar ratio of 1:16 (aflatoxin B1:N-alpha-cetyl lysine), the recovery of adduct was 62%. Analysis of the adduct by thin-layer chromatography showed a single spot (Rf = 0). Absorption spectra of the adduct s...
