Neutral Nylon Membrane

No additional charge is added and the membrane is basically electrical neutral. Its net charge can transform in different pH environments, resulting in different electrostatic adsorption. By regulating the pH of the reaction environment the membrane would show good specific adsorption and test resolution can be improved. UV crosslinking or baking can also be used to coat the film with additional reagents, such as positive charge modification and negative charge modification.

Positively Charged Nylon Membrane

The membrane contains a large number of quaternary ammonium groups. Through electrostatic interactions, positively charged nylon membranes can be used to adsorb, filter or purify negatively charged substances such as nucleic acids, proteins, endotoxins, etc.

Negatively charged nylon film

The negatively charged membrane carrying carboxyl groups provides electrostatic adsorption for positively charged substances. Besides the carboxyl groups can be used to covalently graft special reagents. For example with the aid of EDC and other diimide reagents, covalently bind the amino groups of pre designed gene probes to the carboxyl groups on the membrane. The binding sites of the probes can specifically bind the labeled PCR products of the target genes, and generate specific patterns in the subsequent coloration step for diagnosis results.
