FLOW THROUGH ASSAY DEVICE, DIAGNOSTIC KIT COMPRISING SAID ASSAY DEVICE AND USE OF SAID ASSAY DEVICE IN THE DETECTION OF AN ANALYTE PRESENT IN A SAMPLE

摘要

The present invention relates to an assay device for testing the presence ofan analyte in a given sample comprising: a multilayer support whereon a firstanalyte-binding compound or analyte-binding complex, able to bind said analytepresent in said sample, is immobilized, whereby said analyte is able to bind asecond enzyme labeled analyte-binding compound or enzyme labeled analyte-binding complex forming a sandwich complex, whereby said sandwich complex isable to generate upon contact with a suitable precipitating substrate for saidenzyme-label a colored deposit in a one step procedure. The invention alsorelates to a diagnostic kit or a method for the detection of an analyte in anymedium.
