Abstract:
An assay method, comprising:providing a solid support with opposed sides, one of which is an informational surface, the solid support having one or more capture binding agents immobilized on one side, each capture binding agent having a binding specicificity for an analyte of interest; contacting the capture binding agents with a liquid sample in which one or more analytes may be present; separating the liquid sample from the solid support; incubating the capture binding agents with a developing agent, the developing agent capable of binding with analyte when bound to the capture binding agent, the developing agent including an optical marker, wherein the optical marker generates an optical signal in proportion to bound analytes; detecting the optical signal; and, recording onto the informational surface on the other side of the solid support information concerning the optical signal.
