El tampón de desplazamiento NuPAGE MOPS SDS (20X) se ha formulado para ejecutar proteínas en geles Bis-Tris NuPAGE. Se recomienda para separar a las proteínas medianas y grandes.

Utilice el tampón adecuado para optimizar las separaciones de proteínas
Tanto el tampón de desplazamiento NuPAGE MES SDS como el tampón de desplazamiento NuPAGE MOPS SDS se pueden emplear con geles Bis-Tris NuPAGE. MES tiene un pKa menor que MOPS, lo que hace que el tampón de desplazamiento MES SDS sea más rápido que los tampones de desplazamiento MOPS SDS. La diferencia en la migración de iones afecta a la concentración y da lugar a una diferencia en el intervalo de separación de proteínas entre estos tampones. El empleo de un tampón MOPS permite que las proteínas se desplacen más despacio que cuando se usa un tampón MES.

Preguntas frecuentes

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 is the advantage of NuPAGE Gels over regular Tris-Glycine gels?

The neutral operating pH of the NuPAGE Gels and buffers provides following advantages over the Laemmli system:
-Longer shelf life of 8-12 months due to improved gel stability
-Improved protein stability during electrophoresis at neutral pH resulting in sharper band resolution and accurate results (Moos et al, 1998)
-Complete reduction of disulfides under mild heating conditions (70 degrees C for 10 min) and absence of cleavage of asp-pro bonds using the NuPAGE LDS Sample buffer (pH > 7.0 at 70 degrees C)
-Reduced state of the proteins maintained during electrophoresis and blotting of the proteins by the NuPAGE Antioxidant

Can I use NuPAGE Bis-Tris gels with NuPAGE MOPS or MES Running Buffer prepared without SDS for electrophoresis under native conditions?

We do not recommend using NuPAGE Bis-Tris gels with NuPAGE MOPS or MES Running Buffer prepared without SDS for electrophoresis under native conditions. This buffer system may generate excessive heat, resulting in poor band resolution. Further, the protein of interest may not migrate very well in a neutral pH environment if it is not charged.

Recent studies have shown that the functions of PTH-related protein (PTHrP) and its derived peptides cannot be attributed solely to PTH/PTHrP receptor binding. The present study focused on the identification of other proteins that might bind PTHrP at the cell surface. Using affinity chromatography, we applied extracts of cell-surface biotinylated ... More
