Tris-glycine buffer is NOT compatible with GenScripts precast gels. SurePAGE offers better band resolution and consistency compared to ExpressPlus gels. The figure below shows that compared to SDS sample buffer, LDS sample buffer enables better separation of the protein samples. Romance of the three kingdoms free download GenScripts SurePAGE precast gels provides an economical and quality option for our research needs and saves us at least an hour during gel electrophoresis. They also run at neutral pH which minimizes protein modification compared to Tris-glycine gels. Read More Protein Standard for Anion Exchange Chr.
