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.
