Detailní popis

The Thermo Scientific PageRuler Prestained Protein Ladder is a mixture of ten blue-, orange-, and green-stained recombinant proteins (10 to 170 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.

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. The ladder contains one orange reference band at 70 kDa and one green band at 10 kDa.


  • Size range – 10 proteins spanning 10 to 170 kDa
  • Ready-to-use – supplied in a loading buffer for direct loading on gels, no need to boil
  • Sharp bands – color-coded bands of similar intensity for easy visualization
  • Quality tested – each lot evaluated by SDS-PAGE and Western blotting
  • Two reference bands – orange at 70 kDa and green at 10 kDa
  • Membrane-compatible – colored bands transfer to membranes for 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


For migration patterns under different gel conditions, see Specifications.

Storage Stable at 4°C for up to 3 months. For long term storage, store at -20°C.
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.

Migration patterns of PageRuler Prestained Protein Ladder in different electrophoretic conditions

Migration pattern of Spectra Multicolor Low Range Protein Ladder in Tris-Glycine, Tris-Acetate, and Bis-Tris gels

The apparent molecular weight of each protein (kDa) has been determined by calibration of each protein against an unstained protein ladder in specific electrophoresis conditions.

* Migration patterns were determined using respective NuPAGE precast gels.
