你们的预制蛋白质凝胶是否含有SDS？

我们的预制蛋白质凝胶不含SDS，但在使用合适的变性电泳缓冲液时，可在变性条件下电泳。
注意：NuPAGE Bis-Tris凝胶、Bolt Bis-Tris Plus凝胶和Thermo Scientific Precise Tris-HEPES凝胶不可在非变性条件下电泳；这些凝胶只能用于变性条件下。

*Invitrogen Tris-甘氨酸凝胶：非变性电泳时使用Invitrogen Tris-甘氨酸非变性电泳缓冲液 。变性电泳时使用 Invitrogen Tris-甘氨酸SDS电泳缓冲液

*Invitrogen NuPAGE Tris-Acetate凝胶：非变性电泳时使用Invitrogen Tris-甘氨酸非变性电泳缓冲液 。变性电泳时使用 NuPAGE Tris-乙酸SDS电泳缓冲液

*Invitrogen NuPAGE Bis-Tris凝胶：使用NuPAGE MOPS-SDS电泳缓冲液或NuPAGE MES-SDS电泳缓冲液进行变性电泳

*Invitrogen Bolt Bis-Tris Plus凝胶：使用Bolt MOPS SDS电泳缓冲液或Bolt MES SDS电泳缓冲液进行变性电泳

*Thermo Scientific Precise Tris-甘氨酸凝胶：非变性电泳时使用Tris-甘氨酸SDS电泳缓冲液，不加入SDS。变性电泳时使用Tris-甘氨酸SDS电泳缓冲液。

*Thermo Scientific Precise Tris-HEPES凝胶：使用Tris-HEPES SDS电泳缓冲液进行变性电泳。

Can I prepare my protein sample with the reducing agent and store it for future use?

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

My LDS or SDS sample buffer precipitates when stored at 4 degrees C. Can I warm it up? Can I store it at room temperature?

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.

How are Bolt gels different than NuPAGE gels?

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.

What are the recommended sample loading volumes and protein loading amounts for your precast protein gels?

Do your precast protein gels contain SDS?

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.
