| abstract |
The present invention relates to a solid phase assay device comprising a multi-spot detection zone, and to use thereof in immunochromatographic assays. More precisely, the invention relates to a device for determining analytes in an aqueous sample comprising: an elongate flow matrix ( 6 ) allowing lateral transport of fluid therethrough, wherein said matrix comprises a sample application zone ( 3 ) and downstream thereof, a detection zone ( 8 ) having immobilised capture agents capable of directly or indirectly binding to said analytes, wherein said analytes are detected by allowing a labelled second binding agent to bind directly or indirectly to the analytes. The device is characterised in that the immobilised capture agents are distributed in the detection zone ( 8 ) as a plurality of small spots, thereby permitting multi-analyte and/or multi-specificity detection. |
