An apparatus for performing a binding assay for an analyte of interest present in a sample based upon measurement of electrochemiluminescence at an electrode surface comprising a cell defining a sample containing volume intersecting with inlet and outlet means, an electrode having a substantially horizontally positioned surface exposed to and positioned below a portion of the sample containing volume, means for impressing electrochemical energy upon said electrode sufficient to generate luminescence, means for magnetically collecting particles along said surface and means for measuring the luminescence generated at said electrode.

Methods and apparatus for improved luminescence assays

The invention provides compositions and kits for performing a binding assay for an analyte of interest present in a sample based upon electrochemiluminescence. The compositions and kits comprise an electrochemiluminescent label, collectable particles, binding reagents, and an electrolyte.

Electrochemiluminescent localizable complexes for assay compositions

An apparatus for performing a binding assay for an analyte of interest in a sample based upon measurement of clectrochemiluminescence at an electrode surface comprising: (a) a cell defining a sample; (b) an electrode adjacent a portion of the sample containing volume; (c) a voltage control device for impressing electrochemical energy upon the electrode sufficient to generate luminescence; (d) means for magnetically collecting particles along the electrode surface; and (e) a light detection device for measuring the luminescence.

The invention relates to methods of performing a binding assay for an analyte of interest present in a sample based upon electrochemiluminescence at an electrode of interest. Particles are employed in the method, which are then collected in a zone at which electrochemiluminescence can be induced, wherein the amount of induced electrochemiluminescence is related to the amount of analyte in the sample.
