NuPAGE™ Tris-Acetate SDS Running Buffer (20X)

DTT is not stable, so it must be added and the reduction performed just prior to loading your samples.

Precipitation of the LDS or SDS at 4 degrees C is normal. Bring the buffer to room temperature and mix until the LDS/SDS goes into solution. If you do not want to wait for it to dissolve, you can store the sample buffer at room temperature.

While they are both Bis-Tris based gels, the chemistries are very different since Bolt gels are optimized for western blotting. Another key difference is the wedge well design of the Bolt gels, which allows larger sample volumes to be loaded.

Our precast protein gels do not contain SDS but they can be run under denaturing conditions when used with the appropriate denaturing running buffer.
Note: NuPAGE Bis-Tris gels, Bolt Bis-Tris Plus gels, and Thermo Scientific Precise Tris-HEPES gels cannot be run under native conditions; they can only be run under denaturing conditions.

*Invitrogen Tris-Glycine gels: For Native electrophoresis, use Invitrogen Tris-Glycine Native Running Buffer. For Denaturing electrophoresis, use Invitrogen Tris-Glycine SDS Running Buffer

*NuPAGE Tris-Acetate gels: For Native electrophoresis, use Invitrogen Tris-Glycine Native Running Buffer. For Denaturing electrophoresis, use NuPAGE Tris-Acetate SDS Running Buffer

*NuPAGE Bis-Tris gels: For Denaturing electrophoresis, use NuPAGE MOPS-SDS Running Buffer or NuPAGE MES-SDS Running Buffer

*Bolt Bis-Tris Plus gels: For Denaturing electrophoresis, use Bolt MOPS SDS Running Buffer or Bolt MES SDS Running Buffer

*Thermo Scientific Precise Tris-Glycine gels: For Native electrophoresis, use Tris-Glycine SDS Running Buffer without SDS added. For Denaturing electrophoresis, use Tris-Glycine SDS Running Buffer.

*Thermo Scientific Precise Tris-HEPES gels: For Denaturing electrophoresis, use Tris-HEPES SDS Running Buffer.
