NuPAGE® Novex 3-8% Tris-Acetate Midi-Gels provide excellent separation of large molecular weight proteins when used with NuPAGE® Tris-Acetate SDS Running Buffer. NuPAGE® Novex Tris-Acetate gels can also be run with Tris-Glycine Native Running Buffer to resolve native proteins more effectively than the Tris-Glycine gel system.

NuPAGE® Novex Tris-Acetate Midi-Gels (8 x 13 cm) can run up to 26 samples. The NuPAGE Midi-Gels run in the XCell4 Surelock™ Midi-Cell and, with a Midi Gel Adapter, can run in a Bio-Rad Criterion Cell.

Formulation: NuPAGE® Novex Tris-Acetate gels are made with high-purity, strictly quality-controlled reagents: Tris base, acetic acid, acrylamide, bis-acrylamide, TEMED, APS, and highly purified water. They do not contain SDS.

Recommended Buffers: Run NuPAGE® Novex Tris-Acetate gels with Novex® Tris-Acetate SDS Running Buffer. To ensure good sample reduction and band resolution, use NuPAGE® Sample Preparation Reagents with these gels. The use of NuPAGE® Transfer Buffer provides optimal conditions for transfer of proteins to nitrocellulose, PVDF, or nylon membranes for subsequent analysis. For native running conditions, the Tris-Glycine Native Running and Sample Buffers should be used with NuPAGE® Tris-Acetate gels.
