Title:
ASSAY DEVICES AND METHOD OF DETECTING A TARGET ANALYTE
Document Type and Number:
WIPO Patent Application WO/2015/191419
Kind Code:
A3
Abstract:
Assay devices are provided including a receptacle having a sample entry port; a plunger disposed within the receptacle; at least one reagent; a membrane attached to a first surface of the plunger; a wick providing capillary force; and a detection zone. The membrane includes a target conjugate zone in which affinity components are disposed. Capture compounds are immobilized in a detection zone, which is located between the target conjugate zone and the wick. A method of detecting a target analyte is also provided, including providing the assay device; providing a sample suspected to contain a target analyte; adding the sample onto the device; allowing the sample to travel along the membrane until the sample reaches the detection zone; immobilizing the target analyte through reaction of the target analyte with the capture compounds; reacting the immobilized target analyte with a reagent to generate a detectable signal; and detecting the generated signal.
