The BenchMark™ Pre-Stained Protein Ladder is a standard used to monitor electrophoresis or electrophoretic transfer from gel to membrane in Western blots. It consists of 10 proteins ranging in apparent molecular weight from 6 to 180 kDa. It is designed for use with Tris-Glycine gels. The BenchMark™ Pre-Stained Protein Ladder offers:

• Proteins covalently bound to a blue dye for easy visualization
• One protein band coupled to a pink dye for easy orientation and protein identification
• Affinity-purified proteins to provide sharp bands and clear background
• Easy-to-use format for direct application to an SDS-PAGE gel
• Sufficient reagent for 100 mini gels or 50 regular gels following Western transfer
• Sufficient reagent for 50 mini-gels or 25 regular gels during electrophoresis
