Protran nitrocellulose 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. In addition to high binding capacity, Protran nitrocellulose membranes inherently have very low background. The superior surface properties of the membrane guarantees superior signal-to-noise ratios, without the need for stringent washing conditions. Unlike PVDF membranes, Protran nitrocellulose requires no methanol pre-wetting step. This makes it the membrane of choice for proteins that prefer aqueous environments. Prior to transfer, the membrane is simply wet in water and then in the transfer buffer, with no other necessary pre-treatment steps. Protran membranes exhibit the best handling strangth of all pure nitrocellulose membranes.
Features:

• High binding capacity (80-150g/cm2) of proteins and nucleic acids.
• 100% pure nitrocellulose, with no cellulose acetate added, ensures the highest binding capacity possible.
• Compatible with virtually all standard detection methods.
• Low background - NC surface properties guarantee superior signal-to-noise ratios.
• Triton-free matrix with low extractable levels will support the cell growth essential for colony blotting, plaque lifts, and tissue culture applications.
• Available in many sizes and formats to fit different transfer devices and gel chambers.

Pall® Minimate™ capsules with Omega™ membrane

Reusable TFF Device for Bioprocessing Applications Accelerates and Simplifies Processing of Up to 1 L

Efficient processing. Concentration and diafiltration (desalting or buffer exchange) processes can be performed on the same system with minimal user intervention.

Achieves high concentration factors in a single step due to the low holdup volume of the device. Process sample volumes up to 1 L or more and efficiently concentrate samples to as little as 5 mL.

Minimate™ TFF capsule includes all fittings and tubing to simplify installation into filtration setups. This versatile, self-contained device works with a variety of positive pressure laboratory pumps.

Cost-effective design for non-critical applications. The plastic construction of the Minimate™ TFF capsule and chemical compatibility of the Omega™ PES ultrafiltration membrane facilitate cleaning and reuse.

Scalable. Several Minimate™ TFF capsules may be connected in parallel for increased membrane area. (For more information, contact Pall Technical Service.) -Minimate™ TFF capsules have the same path length and materials of construction as larger Pall Centramate™ and Centrasette™ cassette systems used in pilot and production plants. Predictable performance saves time when scaling up a process.

High product recovery. Optimized flow path design coupled with low protein binding Omega membrane minimize non-specific binding.

Reusable economically-priced device can be dedicated to a single batch or process eliminating the time required for cleaning and validation.

Each Minimate™ capsule is 100% integrity tested during manufacture to ensure reliable performance. For critical applications, the user can re-test the integrity after initial use. A Certificate of Quality is included with each capsule.
