Immunoassay assembly and methods of use |
摘要 |
The present invention relates to an improved system for efficiently and accurately performing immunoassays, such as ELISAs. The invention provides an immunoassay assembly which includes a flow-through unit and an aspiration pump. The immunoassay flow-through unit includes an outer seal; at least one bed support; an inner seal; and a packed non-porous bed. The unit is releasably attached to an aspiration pump which enables the controlled flow rate of liquid passing through the packed bed of the flow-through unit. The invention also provides a method of using the immunoassay assembly to identify analytical targets of interest. |

1. An immunoassay or selective adsorption assembly comprising a flow-through assay unit and an aspiration pump; wherein the flow-through assay unit includes a pair of porous bed supports trapping between them solid phase support beads with a reaction reagent mounted on their surface, an open proximal end, and an open distal end of smaller diameter than the proximal end; wherein the aspiration pump includes a pump block, a piston, and an inlet port formed in the pump block and sized to receive the distal end; the aspiration pump is in fluid communication with the flow-through assay unit via the distal end to draw fluid therethrough; the aspiration pump is vertically oriented with the inlet port being conical at a top of the aspiration pump; and the assay unit has a corresponding tapered opening at the distal end so that the assay unit is mountable upon the pump in fluid-tight fashion. |
