Protran Nitrocellulose Membrane

Protran BA85 Nitrocellulose Membrane

100% Pure Nitrocellulose Membranes
Protran™ nitrocellulose (NC) membranes are the most frequently specified transfer media in the world for a wide range of applications. Protran 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. They are compatible with a variety of detection methods, including isotopic, chemiluminescent (luminol-based), colorimetric, and fluorescent.

Unlike PVDF membranes, Protran nitrocellulose does not require a methanol prewetting step. This makes Protran the membrane of choice for proteins which prefer aqueous environments. Prior to transfer, the membrane is simply wetted in water, and then placed in the transfer buffer. No other pretreatment steps are necessary. 

High binding, low background
In addition to 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.

High retention of small proteins
The 0.2 µm pore size Protran (BA83) nitrocellulose membrane has high surface area, ensuring binding of small proteins below 20 kD by reducing ‘blow-through’. The 0.45 µm pore size membrane (BA85) is suitable for larger molecular weight samples. BA79, with 0.1 µm pore size, is the membrane of choice for smaller proteins below 7 kD.

A key benefit of the proprietary Protran nitrocellulose formula is the proven shelf life of bound proteins. Empirical evidence shows that proteins maintain molecular recognition activity for five years on Protran.

Protran blotting sandwiches
A precut nitrocellulose membrane and 2 sheets of 3MM Chr blotting paper are prepackaged into a sandwich to help save time. This is made with our Protran BA83 or BA85, the highest quality NC membranes available for blotting.
