    Abstract: Disclosed are compounds of the formula (I): wherein R3, R4, R5, R9, and R10 are selected from the group consisting of H and groups or atoms other than H, and R6 and R8 are halo or hydrogen; X1, X2, and X3 are independently O or S; provided that R9 and R10 are not simultaneously H, when all of X1, X2, and X3 are O; and of the formula (II) wherein R11-R14 are selected from the group consisting of H and groups or atoms other than H; X4-X9 are independently O or S; n and m are 0 or 1 but m and n cannot be 0 simultaneously; R15-R24 can be H or any substituent so long as the compound of formula II upon hydrolysis provides a fluorescent compound. These compounds are useful as substrates with high specificity for organophosphatase particularly human paraoxonase and bacterial organophosphorus hydrolase. Also disclosed is a method for detecting and/or measuring the paraoxonase activity in a fluid comprising contacting the fluid with a fluorescent substrate and measuring the fluorescence of the fluorescent product formed.

    Abstract: The invention provides a method of identifying and detecting targets in blood samples by binding to multiple ligands. The method comprises providing ligands attached to a support, and contacting the ligands with targets in blood to allow at least one target to bind to at least one ligand. The method further comprises removal of non-bound targets and cellular components such as blood cells, platelets, abundant plasma proteins followed by dissociation and elution of the target(s). The eluted targets are detected by a variety of means in concentrations which are a function of their presence in one sample as compared with their concentration in a second sample and are simultaneously enriched for trace components.

    Abstract: The invention provides a method of binding multiple targets in samples by binding to multiple ligands. The method comprises providing ligands attached to a support, and contacting the ligands with targets to produce at least two target-ligand-support complexes. The method further comprises removal of non-bound targets followed by elution of the bound targets. The eluted targets are present in concentrations of a particular analyte that is a function of their comparative concentrations in different samples. Furthermore, the mixture is enriched for trace components.
