- Are any animal-derived proteins present in the PageRuler™ Prestained Protein Ladder and PageRuler™ Plus Prestained Protein Ladder?
- What are the storage conditions and shelf life for the Spectra™ Protein Ladders?
- I am not sure whether I have the SeeBlue™ or SeeBlue™ Plus 2 pre-stained standard. Is there a way of telling the difference from the cap color?
- Can I use the HiMark™ Pre-Stained Protein Standard with NuPAGE™ Bis-Tris gels and Tris-Glycine gels?
- What are the molecular weights of the proteins in the Novex™ Sharp Unstained Standard?
- A couple of bands in my protein standard are missing on the gel. Can you help me troubleshoot?
- I used one of your protein standards and am seeing some extra bands in the lane. Can you offer some suggestions?
- I used one of your Thermo Scientific™ PageRuler™ prestained protein ladders and did not get good separation of the bands. What could have happened?
- I used one of your pre-stained standards on a Tris-Glycine gel and noticed that the molecular weights of the proteins were different than on a NuPAGE™ Bis-Tris gel. What is the reason for this?
- I used your Thermo Scientific™ SuperSignal™ Enhanced MW Protein Ladder and did not see any bands after western detection. What could have happened?
