Polarization fluoroimmunoassay of the herbicide dichlorprop
A polarization fluorescence immunoassay has been developed for the screening of the herbicide dichlorprop [(f)-2-(2,4-dichlorophenoxy)propanoic acid]. The assay is based on the difference in… Expand
Enzyme-linked immunosorbent assay by image analysis using a charge-coupled device array detector.
This paper describes a fluorescence enzyme-linked immunosorbent assay (ELISA) for the quantification of (+/-)-2-(2, 4-dichlorophen-oxy)propionic methyl ester (dichlorprop methyl ester). Antibodies… Expand
Phase-modulation fluorescence lifetime immunoassay of dichlorprop.
A homogeneous immunofluorimetric technique to determine dichlorprop herbicide is described. Simultaneous determinations of both free and antibody-bound fluoresceinamine-labeled dichlorprop were… Expand

The chemiluminescence of the luminol-H2O2-horseradish peroxidase system is increased by fluorescein. Fluorescein produces an enhancement of the luminol chemiluminescence similar to that of… Expand
Enhanced chemiluminescence kinetic ELISA of dichlorprop methyl ester
A competitive enzyme-linked immunosorbent assay (ELISA) for dichlorprop methyl ester (DIME) with an anti-rabbit secondary antibody conjugated to peroxidase was developed in polystyrene plates. The… Expand
Variable-angle synchronous fluorescence spectrometry and rank annihilation methods for mixture resolution.
The potential of variable angle synchronous spectroscopy (VASS) for fluorescent mixtures resolution was assessed and compared with the rank annihilation method (RAM). For this purpose, a set of… Expand
Enzymatic determination of fenitrothion by cholinesterase and acetylcholinesterase on fluorogenic substrates
Abstract The action of the enzymes acetylcholinesterase and cholinesterase on the substrates indoxylacetate and 2-naphthyl acetate was studied kinetically. Both enzymes convert the substrates to… Expand
α-Cyclodextrin as a restricted access mobile phase for reversed-phase liquid chromatography with fluorimetric detection of phenolic compounds
Abstract A reversed-phase liquid Chromatographic (LC) method to determine the phenolic derivatives, p -hydroxybenzoic (PHB), ferulic and vanillic acids, and methyl paraben (MPB), was developed. The… Expand
Chemiluminescent lipase determination based on the enhanced luminol/H2O2/horseradish peroxidase/fluorescein diacetate energy transfer system
Abstract A methodology for the determination of lipase, based on the coupled processes of energy transfer and enhancement of the chemiluminescence of the luminol-H2O2-horseradish peroxidase (HRP)… Expand
