Abstract
Methods and devices for separating bound label from unbound label within an assay mixture and for predispensing assay reactants in self-contained assay vessels, as well as a method for detecting the presence and/or amount of an analyte within a fluid sample, and a reusable detection vessel for use therein and with specific binding assays in general are disclosed. Significant to the separation of bound label from unbound label is the use of a cushion comprising generally one primary layer and in some cases one or more secondary layers.
