Protran™ nitrocellulose transfer membranes offer:

• Pure: 100% nitrocellulose, with no cellulose acetate added, ensuring the highest binding capacity possible
• Low background: superior surface properties guarantee superior signal to noise ratios, without stringent washing conditions
• High retention of small or large proteins: 0.2 µm pore size membranes reduce "blowthrough” of small proteins, whereas 0.45 µm pore size membranes are ideal for larger molecular weight samples
• No methanol pre-wetting step: prior to transfer, the membrane is simply wet in water, and then in the transfer buffer
• No other pre-treatment steps are necessary
