Nylon Membrane, Nylon, 0.45 μm (CAT#: STEM-BC-0125-ZJF)

The nylon membrane is a naturally hydrophilic membrane used for diagnostic and analytical applications. It includes neutral, positively charged, and negatively charged versions. The neutral membrane does not contain added charge and can present different electrostatic adsorption behavior under different pH conditions. The positively charged membrane contains quaternary ammonium groups for adsorption of negatively charged materials such as nucleic acids, proteins, and endotoxins. The negatively charged membrane contains carboxyl groups and can be used for electrostatic adsorption or covalent grafting of special reagents. A PET support layer improves mechanical strength. The symmetric nylon coating provides high porosity and high surface area for reaction sites. The smooth surface supports printing-like reagent deposition and assay readability.
