ABSTRACT OF THE DISCLOSURE 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, even when organic solvent based adhesives are used, due to the incorporation of anionic surfactants in a concentration range of from about 0.1% to about 3.5% (w/w) for nitrocellulose, and from about 2.0% to about 5.0% (w/w) for PVDF membranes.
