Abstract: Laminated porous membranes useful in chromatographic assay devices include nitrocellulose or polyvinylidene difluoride (PVDF) membranes laminated to supports. Despite lamination, the membranes remain wettable and the activity of biologically reactive reagents is not impaired due to the use of water based adhesives in making the laminates. Water based adhesives include AS73 from Adhesive Research, Inc, polyvinylacetate (PVA) and polyvinylpyrrolidone (PVP) among others.

Abstract: The novel analytical devices and methods of the present invention involve a solid phase material, such as a test strip, through which a test sample and a conjugate travel and sequentially contact at least two defined sites for the comparative display of immobilized conjugate. The two defined sites of the present invention include a capture site to which is attached a capture reagent and a conjugate recovery site to which is attached a conjugate recovery reagent. The immobilization of conjugate in these sites is relative to the amount of analyte in the test sample. As the amount of analyte in the sample increases, there is a decrease in the detectable conjugate at the capture site and a corresponding increase in detectable conjugate at the conjugate recovery site. The devices and methods can be used for detecting the presence or amount of an analyte in a test sample containing or suspected of containing the analyte of interest. Optionally, a polyvalent conjugate can be used.
