Bio-Rad's 0.45 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 0.45 µm pore size is recommended for most analytical blotting, including protein, ssDNA, and RNA transfers.
