Blotting Membranes

Blotting membranes support New Zealand protein transfer, western blotting, immunoblotting and molecular biology workflows where separated proteins or nucleic acids need to be transferred from gels to a solid membrane for detection.

John Morris Group supplies laboratory equipment and consumables through page-supported supply channels including Kinesis, helping NZ teams source products for Laboratory and Life Science and Diagnostics workflows.

Blotting Membranes for New Zealand Protein Transfer Workflows

Blotting membranes are used where laboratories need a solid support for proteins or nucleic acids after electrophoretic separation. Common membrane types include PVDF and nitrocellulose, with selection depending on protein binding requirements, detection method, background signal, membrane handling and whether the blot may need stripping or reprobing.

  • PVDF membrane selection: Choose PVDF for stronger membrane handling, high protein retention and workflows where reprobing may be required.
  • Nitrocellulose membrane selection: Select nitrocellulose for routine western blotting where low background and straightforward blocking are preferred.
  • Pore size matching: Confirm whether 0.45 µm or 0.2 µm formats are more suitable for the target molecule and transfer method.
  • System compatibility: Match membrane dimensions and format to the electrophoresis and blotting equipment used in the laboratory.

How to Choose Blotting Membranes

Before ordering, technical buyers should confirm membrane material, pore size, transfer method, sheet or roll format, target size, detection chemistry, binding capacity, chemical compatibility and whether the workflow requires stripping, reprobing or fluorescence detection. Related procurement may include Gel Boxes, Electrophoresis Power Supplies and Gel Documentation Systems.

Applications Across NZ Molecular Biology and Life Science Laboratories

  • Western blotting: Transfer proteins from gels to PVDF or nitrocellulose membranes before antibody-based detection.
  • Protein analysis: Support research, teaching and method development workflows involving immunodetection.
  • Nucleic acid blotting: Use suitable membranes for compatible northern and Southern blotting workflows where required by the method.
  • Life science workflows: Support molecular biology, proteomics, biochemistry and laboratory teaching applications.

Category Review Recommendation

The currently visible product listing for this category appears to include a cordless field microscope rather than blotting membranes. Before publishing, the product assignment should be reviewed so that the category displays relevant blotting membranes, transfer accessories or related electrophoresis consumables.
