Bio-Rad's 0.2 µm pore–size nitrocellulose membrane is dense 100% nitrocellulose. Pure nitrocellulose is the most frequently used membrane for the transfer of both proteins and nucleic acids. It is a proven medium for western, northern, and Southern blotting that produces excellent signal-to-noise results. Bio-Rad nitrocellulose is easy to handle, wets readily with water-based solutions, and resists the brittleness usually associated with nitrocellulose. The 0.2 µm pore size is optimized for transferring nucleic acids and low molecular–weight proteins: the smaller pore size minimizes protein sample loss due to transfer through the membrane.
Features and Benefits
- Compatible with all standard immunoblotting and nucleic acid detection methods
- Provides superior binding capacity without background interference
- Smaller pore size minimizes low molecular–weight protein sample loss
- Available in three formats:
- Convenient precut 0.2 µm membrane/blot absorbent filter paper sandwiches
- Packs of precut membrane-only sheets
- Economical rolls
- Transfer of low molecular–weight proteins and nucleic acids <500 bp
- Protein transfer from SDS-PAGE gels to membrane in preparation for western blotting
- Transfer of nucleic acids in preparation for northern or Southern blotting
- Immunodetection of target protein and probe hybridization of nucleic acids
