Detailní popis

The Thermo Scientific Pierce 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).

This prestained protein MW marker is designed for monitoring the progress of SDS-polyacrylamide gel electrophoresis, for assessing transfer efficiency onto PVDF, nylon and nitrocellulose membranes, and for estimating the approximate size of separated proteins (1-3) that have been made visible with gel stains or Western blot detection reagents.


  • Size range – six proteins spanning 20 to 120 kDa
  • Ready-to-use – supplied in a loading buffer for direct loading on gels
  • Prestained – for direct viewing during electrophoresis
  • Quality tested – each lot evaluated by SDS-PAGE and Western blotting


  • 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
    Hazardous No
    Quality Control Tested in SDS-polyacrylamide gel electrophoresis and Western Blotting.
    Storage Store at -20°C.
    Storage Buffer
    • Dye-stained proteins in 62.5 mM Tris-HCl (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1.5 mM NaN3, and 33% glycerol
