Cytiva, 78316404, Whatman Immunopore SP membrane, 25 mm × 50 m (1/pk)

Immunopore Membranes Immunopore is a plastic-backed nitrocellulose membrane. A proprietary polymer is included in the membrane matrix to ensure rapid rewetting and low background signal, eliminating protein-binding interference commonly experienced with surfactants. Nitrocellulose Membranes Nitrocellulose membranes are a key functional part of lateral-flow assays. The membrane must provide sufficient protein binding to enable the production of a sharp and intense capture line, but at the same time the level of nonspecific background must be low for easy interpretation of results. Nitrocellulose membranes are available in a range of wicking rates and formulations. It has long been known that the wicking rate of a membrane has a significant impact on test sensitivity.
