Long-lifetime fluorescent europium(III) chelate nanoparticles have been shown to be applicable as labels in various heterogeneous and homogeneous immunoassays. Assay performance can be improved when these intrinsically labeled nanoparticles are used in combination with time-resolved fluorescence detection. In several previous publications, we have shown the potential of nanoparticle labels in different assay applications. In heterogeneous assays, the dynamic range of assays at low concentrati...

	Multicenter Analytical Evaluation of an Enzymatic Method for the Measurement of Plasma Homocysteine and Comparison with HPLC and Immunochemistry Clinical Chemistry ; Homocysteine (Hcy) is a sulfur amino acid and a metabolite of the amino acid methionine. Hcy is very reactive because it contains a free sulfhydryl (thiol) group, and it readily oxidizes to form various disulfides. The fraction of free Hcy in plasma is therefore <2% of total plasma Hcy (tHcy)
