Thermo Scientific™ PageRuler™ Prestained Protein Ladder, 10 to 180 kDa, 10 x 250 µL

Thermo Scientific™ PageRuler™ Prestained Protein Ladder, 10 to 180 kDa, 10 x 250 µL

Thermo Scientific PageRuler Prestained Protein Ladder is a mixture of 10 blue-, orange-, and green-stained proteins (10 to 180 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.

Features

• Monitoring protein migration during SDS-polyacrylamide gel electrophoresis
• Monitoring protein transfer onto membranes after western blotting
• Sizing of proteins on SDS-polyacrylamide gels and western blots

Contents

• Ten vials of 250 µL each
• Storage buffer: 62.5 mM Tris-H3PO4 (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3 and 33% glycerol
