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.
Product features • Reference bands—the 100, 50, and 20 kDa bands are more intense for easy orientation • Tagged—bands 10, 15, 20, 30, 40, 50, 70, 100, 150, and 250 contain an integral Strep-tag II sequence and can be detected on western blots using Strep-Tactin conjugates or an antibody against Strep-tag II sequence
Applications • Accurate protein sizing on SDS-polyacrylamide gels and western blots
