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 beta-mercaptoethanol (BME) be used rather than DTT as the reducing agent in the NuPAGE LDS Sample Buffer?

Either BME or DTT can be used in the NuPAGE LDS Sample Buffer.

Make sure that a fresh solution of BME is used. FINAL concentration:

DTT 50-100 mM

BME 2-5%

Abstract
Heat shock protein-70 expressed on the surface of cancer cells binds parathyroid hormone-related protein in vitro.

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
