Thermo Scientific Prestained Protein Molecular Weight Marker is a mixture of six blue-stained natural proteins (20 to 120 kDa) for use as size standards in protein electrophoresis (SDS-PAGE). The protein standards are supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.
Applications • 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
For Research Use Only. Not for use in diagnostic procedures.
