FLOW-THROUGH ASSAY WITH AN INTERNAL CALIBRATION SYSTEM USING POLYELECTROLYTE |
摘要 |
Abstract of the Disclosure A flow-through assay for detecting the quantity of an analyte residing in a test sample is provided. The flow-through assay contains a porous membrane that is in fluid communication with probe conjugates that contain a specific binding member and a detectable probe. The porous membrane also defines a detection zone and a calibration zone. The calibration zone contains a polyelectrolyte substantially non-diffusively immobilized on the porous membrane. The polyelectrolyte is capable of generating a detectable calibration signal that can be readily compared (visually, quantitatively, and the like) to a detection signal to determine the amount of analyte in the test sample.
