Nylon Membrane

Nylon membrane is hydrophilic in nature. With high hydrophilicity, it provides not only excellent flow rate but also high strength with substrate and broad chemical & PH compatibility.The membrane is casting on a non-woven substrate, thence, it perform better mechanical ability than other none-substrate membranes.

The Positively-Charged version is widely used in endotoxin retention applications. The Nylon membrane is surface modified with positive groups which could effectively adsorb negatively charged endotoxin. The Negatively-Charged version is used in a variety of applications where electrical twinning or effective retention of microbes and particles are required. Reverse Dot Blot (RDB) is a typical application within which negatively-charged nylon membrane is used as a carrier media of gene probes.

The Positively-Charged version can closey combine with DNA molecule and endotoxins, with improved sensitivity and reduced background.
