NativePAGE™ Bis-Tris Mini Protein Gels, 3 to 12%, 1.0 mm

The NativePAGE Invitrogen Bis-Tris Gel System is a pre-cast polyacrylamide mini gel system that provides a sensitive and high-resolution method for analyzing native membrane protein complexes, native soluble proteins, molecular mass estimations, and assessing purity of native proteins. It is based on the blue native polyacrylamide gel electrophoresis technique (BN PAGE) developed by Schagger and von Jagow.

There may be too much beta-mercaptoethanol (BME), sample buffer salts, or dithiothreitol (DTT) in your samples. If the proteins are over-reduced, they can be negatively charged and actually repel each other across the lanes causing the bands to get narrower as they progress down the gel.

We recommend rinsing the membrane briefly in water, air drying and store it at room temperature in a ziplock bag. Do not place nitrocellulose in the freezer because it will shatter. Unlike PVDF, nitrocellulose membranes should never be pre-wetted in alcohol as it will cause them to shrivel.

Yes, NativePAGE gels are compatible with our Mini Gel tank, however there is a small variation from the original protocol.

The following protocol are for using NativePage gels with the Mini Gel Tank depending on if you are also performing a western transfer or not:
If you are NOT performing a western transfer:
1. Prepare 250 mL of each buffer (Anode and Dark Blue Cathode) per gel
2. After inserting a loaded NativePAGE gel into the Mini Gel Tank and pulling the clamp forward, fill the front cathode buffer chamber to the Fill Line with Dark Blue Cathode Buffer (~200 mL per gel)
3. Add 220 mL of Anode Buffer to the back anode buffer chamber for that gel. Start the gel run

If you are performing a western transfer:
1. Prepare 250 mL of Dark Blue Cathode Buffer, 250 mL of Light Blue Cathode Buffer, and 500 mL of Anode Buffer per gel
2. After inserting a loaded NativePAGE gel into the Mini Gel Tank and pulling the clamp forward, fill the front cathode buffer chamber to the Fill Line with Dark Blue Cathode Buffer (~200 mL per gel
3. Add 220 mL of Anode Buffer to the back anode buffer chamber for that gel
4. Start the gel run; pause the run after the dark blue dye has run ~1/3 of the way through gel
a. Pour out the buffers from the Mini Gel Tank
b. Refill the back anode buffer chamber with 220 mL of Anode Buffer per gel
c. Fill the front cathode buffer chamber to the Fill Line with Light Blue Cathode Buffer (~200 mL per gel)
5. Resume the gel run

We recommend using the NativeMark Unstained Protein Standard, Cat. No. LC0725 for native gel electrophoresis with Tris-Glycine, NuPAGE Tris-Acetate or NativePAGE gels.
