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 bandsthe 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 sequence.
