Protran and Optitran Blotting membranes

  • 100% pure nitrocellulose membrane
  • Low background
  • Superior for HRP chemiluminescence detection
  • High binding capacity
Protran nictorcellulose membranes are manufactured using 100% pure nitrocellulose to ensure the highest binding capacity possible. Other membranes referred to as "nitrocellulose" may actually contain large amounts of cellulose acetate which will lower the protein binding capacity. Protran membranes have the best handling strength of all pure nitrocellulose membranes.

High binding capacity
The 0.20 µm pore size of the Protran (BA83) nitrocellulose membrane ensures high binding capacity of small samples below 20 kD by reducing "blow-through". The 0.45 µm pore size membrane (BA85) is ideal for larger molecular weight samples.

Low background
In addition to the high binding capacity, Protran nitrocellulose membranes inherently have very low background. The superior surface properties of the membrane guarantee superior signal-to-noise ratios, without the need for stringent washing conditions.

Optitran supported nitrocellulose membranes combine sensitivity, strength and savings. Optitran membrane consists of pure 100% nitrocellulose cast onto both sides of an inert polyester support material. The support in no way affects transfer conditions or results and gives the membrane exceptional handling characteristics, allowing it to be reprobed repeatedly.

The combination of flexibility, strength and excellent signal-to-noise ratios makes the Optitran membrane ideal, especially when procedures involve repeated stripping and reprobing.
