Thermo Scientific PageRuler Unstained Protein Ladder is a mixture of 14 recombinant, highly purified, unstained proteins (10 to 200 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—50 kDa band is stronger than the others for easy orientation • Tagged—the ladder proteins 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 Sequence
Applications • Accurate protein sizing on SDS-polyacrylamide gels and western blots
