    Immun-Blot® PVDF Membrane

    Bio-Rad's Immun-Blot PVDF membrane is ideal for chemiluminescent and colorimetric western blots. This PVDF membrane retains target protein very strongly while reducing nonspecific protein binding.

    Immun-Blot Low Fluorescence PVDF Membrane
    Bio-Rad’s low-fluorescence PVDF membrane is validated for fluorescent western blotting applications. The low autofluorescence of this membrane allows for longer exposure and higher sensitivity without increased background.

    Sequi-Blot™ PVDF Membrane

    Bio-Rad's Sequi-Blot PVDF membrane delivers outstanding performance in protein sequencing, providing the binding capacity to sequence even low-abundance samples.

  • nitrocellulose-membrane-045-thumb.jpg
    Nitrocellulose Membrane, 0.45 µm

    Bio-Rad's nitrocellulose is a proven medium for western, northern, and Southern blotting. The 0.45 µm pore size is recommended for most analytical blotting including protein, ssDNA, and RNA transfers.

  • nitrocellulose-membrane-02-thumb.jpg
    Nitrocellulose Membrane, 0.2 µm

    Bio-Rad nitrocellulose membrane with a 0.2 µm pore size is optimized for western, northern, and Southern blotting of nucleic acids and low molecular weight proteins.

  • supported-nitrocellulose-membrane-045-thumb.jpg
    Supported Nitrocellulose Membrane, 0.45 µm

    Made of pure nitrocellulose cast on an inert synthetic support, this 0.45 µm nitrocellulose membrane is a solid support for nucleic acid and protein applications that can withstand multiple reprobing.
