Thermo Scientific PageRuler Unstained Broad Range Protein Ladder is a mixture of 11 proteins (5 to 250 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting. The protein ladder is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.Compare and view all other protein standards and ladders ›Product features
• Reference bands—the 100, 50, and 20 kDa bands are more intense for easy orientation
• Tagged— each protein in the contains an integral Strep-tag™ II sequence and can be detected on western blots using Strep-Tactin™ conjugates or an antibody against Strep-tag™ II sequenceApplications
• Accurate protein sizing on SDS-polyacrylamide gels and western blots
