Thermo Scientific PageRuler Unstained Low Range Protein Ladder is a mixture of eight purified proteins and peptides (3.4 to 100 kDa) for use as size standards in peptide and small-protein gel electrophoresis. 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—25 kDa band is stronger than the others for easy orientation • Tagged—the ladder proteins (except for the 5 and 3.4 kDa peptides) contains an integral Strep-tag™ II sequence and can be detected on western blots using Strep-Tactin™ conjugates
Applications • Accurate protein sizing on SDS-polyacrylamide gels and western blots
