Nitrocellulose Membrane for Rapid Test Kits
The Nitrocellulose membrane is the most pivotal part of a rapid test kit as this is where the antigen-antibody binding occurs. Manufactured under strictly controlled conditions, Nupore membranes are cast on transparent polyester backing and offer highly consistent results, reliable inter-lot performance, and sharp control/test lines with minimal non-specific background signal.
Key Advantages
Range of wicking rate options

Nupore NC membranes are recommended to be stored in original foil pouch at an ambient temperature (around 20°C) for longer shelf life. As the membrane is inflammable, it should be kept away from direct heat and sunlight.
