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

Applications

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.

Solvent Compatibility

  • Resistant to common solvents such as acetone, alcohol, chlorinated aliphatic hydrocarbons, formamide, 2M NaOH, DMSO, and dimethylformamide. Not compatible with concentrated formic acid (> 50%), HCl (> 4M), oxidizing agents, and long exposures (days to weeks) to pH < 2.

Performance

Biodyne® B Membrane Withstands Multiple Cycles of Stripping and Reprobing


Biodyne B Membrane Withstands Stripping and Reprobing
Lambda-HindIII fragments were separated in an agarose gel and transferred to Biodyne B membrane using the Pall Improved Alkaline Transfer. The blot was stripped completely and reprobed four times without loss of signal intensity. Bands were detected using a chemiluminescent detection system. 

1A - 4A: blot after (re)probing
1B - 4B: blot after stripping, prior to re(probing)

Fluorescent Detection of DNA Using Biodyne Plus Membrane


Fluorescent Detection of DNA Using Biodyne Plus Membrane
ng total DNA

Dilutions of HindIII-digested I-DNA (1000 - 1 ng/lane) were separated in an agarose gel and transferred to Biodyne Plus membrane. Signal was generated using a fluorescein-labeled probe, antifluorescein-alkaline phosphatase conjugate, and precipitating substrate. The image was generated by scanning the blot with a FluorImager* system. *FluorImager is a registered trademark of Molecular Dynamics.
