Abstract: A method and reagent that can be used to eliminate the signal caused by non-specific binding of a labeled conjugate, e.g., a specific binding member attached to a label, to a solid phase, e.g., a magnetic microparticle. The method and the reagent involve the use of a cleavable linking agent to link the label to the specific binding member that specifically binds to the analyte. The use of a cleavable linking agent would allow the release of the label from the specific binding member from the complex comprising the magnetic microparticle, analyte, and labeled conjugate into solution. After the release of the label, the magnetic microparticles having any label non-specifically bound thereto, are removed from the reaction mixture. Only the label, e.g., acridinium, from the labeled conjugate would remain in the elution well. The conjugate that is non-specifically bound through interaction between the label and the solid phase, e.g.

Abstract: The invention relates to certain substituted derivatives of aminopolycarboxylic acids and metal chelates thereof. The compounds are particularly suitable for use as diagnostic agent. For example, the compounds can be used as radiodiagnostic agents, detoxification agents and contrast agents for diagnostic imaging processes. In particular, the high relaxivity paramagnetic metal chelates of substituted aminopolycarboxylic acids are especially suited for use as magnetic resonance imaging contrast agents.

Abstract: Linear oligomer polychelant compounds and chelates formed therewith have alternating chelant and linker moieties bound together by amide or ester moieties. The compounds have between 3 and 100 chelant moieties, at least one of which complexes a paramagnetic metal ion. The polychelants and especially their paramagnetic metal polychelates are particularly suitable for diagnostic imaging.

Abstract: There are disclosed polychelant compounds, that is multi-site metal chelating agents, and chelates formed therewith. The polychelants and especially their paramagnetic metal, heavy metal or radioactive metal polychelates are particularly suitable for use in diagnostic imaging, heavy metal detoxification or radiotherapy. The polychelants have a linear or branched oligomeric structure comprising alternating chelant and linker moieties bound together by amide or ester moieties the carbonyl groups whereof being adjacent the chelant moieties, each polychelant comprising at least two said chelant moieties capable of complexing a metal ion.
