DETERMINATION OF SERUM CORTISOL LEVEL BY A DIREC T ENZYME IMMUNOASSAY USING PENICILLINASE AS LABEL
Serum cortisol level was measured by an enzyme immunoassay (EIA) using the enzyme penicillinase as a label without prior extraction and purification. Polyclonal antibodies were raised against cortisol-3-ortho-carboxymethyl-oxime (cortisol-3-0-CMO) conjugated to bovine serum albumin (BSA). This antibody showed a very low cross-reactivity with structurally related steroids (3.7% for corticos...
متن کاملMixed-mode solid-phase extraction and cleanup procedures for the liquid chromatographic determination of thiabendazole and carbendazim in fruit juices.
Solid-phase extraction (SPE) procedures were developed for rapid cleanup and determination of thiabendazole and carbendazim in orange, apple, and grape juices. Samples were prepared by using an SPE cartridge containing a mixed-mode sorbent with both reversed-phase and strong cation-exchange chemistries. Analysis was by liquid chromatography with photodiode-array UV detection. Orange juice was a...
متن کاملDetermination of pesticides in fruit and fruit juices by chromatographic methods. An overview.
In order to combat a variety of pests, pesticides are widely used in fruits. Several extraction procedures (liquid extraction, single drop microextraction, microwave-assisted extraction, pressurized liquid extraction, supercritical fluid extraction, solid-phase extraction, solid-phase microextraction, matrix solid-phase dispersion, and stir bar sorptive extraction) have been reported to determi...
متن کاملDetermination the Frequency of Yersinia enterocolitica in Traditional Fruit Juices Obtained from Juices Shop in Southern Part of Tehran
Background and Aim: Fruit juices are an important part of modern diets that can infect various gastrointestinal tract infections if infected with pathogenic bacteria. The aim of this study was to determine the Frequency of Yersinia enterocolitica in traditional fruit juices shop in southern part of Tehran. Materials and Methods: This was a descriptive cross-sectional study, 100 samples of frui...
متن کاملMeasurement of monoclonal antibody affinity by non-competitive enzyme immunoassay.
Enzyme-linked immunoadsorbent assay (EIA) has widespread use for the measurement of antibody concentration. The affinity constant (Kaff) of the antibody has an effect upon the quantification by EIA. It is thus important to be able to measure Kaff by solid-phase EIA. Based upon the Law of Mass Action and using serial dilutions of both antigens (coating the plate) and antibody, Kaff has been meas...
