Blotting Membranes

Blotting membranes support 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 Australian teams source products for Laboratory and Life Science and Diagnostics workflows.

Blotting Membranes for Western Blot and 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, durability, background signal and whether the membrane may need stripping or reprobing.

  • PVDF membranes: Choose PVDF where higher durability, strong protein retention and compatibility with reprobing workflows are required.
  • Nitrocellulose membranes: Select nitrocellulose for routine western blotting where low background and straightforward blocking are important.
  • Pore size selection: Match pore size to the target molecule, with common options including 0.45 µm for many analytical blotting workflows and 0.2 µm for smaller proteins or low molecular weight targets.
  • Workflow compatibility: Confirm membrane format, transfer method, detection chemistry and blotting equipment compatibility before ordering.

Choosing Blotting Membranes for Laboratory Use

Technical buyers should confirm membrane material, pore size, sheet or roll format, transfer method, target size, detection method, binding capacity, chemical resistance and compatibility with the laboratory’s blotting system. For related procurement, teams may also review Gel Boxes, Electrophoresis Power Supplies and Gel Documentation Systems.

Applications Across Molecular Biology and Protein Analysis

Blotting membranes are selected where transfer quality, target retention and signal clarity are important for downstream detection.

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

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.
