Pall® Biodyne® Nylon Transfer Membranes

• High sensitivity and low background for enhanced detection and resolution.
• Will not crack, shrink, or tear when subjected to multiple cycles of hybridization, stripping, and reprobing
• Membranes are intrinsically hydrophilic for easy wetting
• Offers superior performance with radioactive (Biodyne B membrane) and non-radioactive (Biodyne A membrane) detection systems

Four Chemistries Provide Versatile Adsorption Properties:

• Biodyne A Membrane - (Amphoteric Nylon 6,6) Membrane zeta potential can be modulated by changes in pH. Ideal for single probe or multiple rehybridizations, and applications where background is troublesome.
• Biodyne B Membrane - (Positively-charged Nylon 6,6) Pore surfaces are populated by a high density of quaternary ammonium groups. Our highest sensitivity nylon membrane for nucleic acid applications.
• Biodyne C Membrane - (Negatively-charged Nylon 6,6) Can be derivatized by coupling reactions through the carboxyl groups on the pore surfaces.
• Biodyne Plus Membrane - (Positively-charged Nylon 6,6 with an extremely high isoelectric point) With certain nonradioactive detection systems, it is more sensitive than Biodyne A membrane while exhibiting lower background than Biodyne B membrane.
