The protein MW marker is designed for accurate sizing of proteins in SDS-polyacrylamide gel electrophoresis, as well as on PVDF, nylon and nitrocellulose membranes. The protein standard produces sharp bands on protein mini gels following staining with Thermo Scientific Pierce Gel Stains or other coomassie dye or silver stains.


  • Size range – seven proteins spanning 14.4 to 116kDa

  • Ready-to-use – supplied in a loading buffer for direct loading on gels

  • Sharp bands – equal intensity upon coomassie or silver staining

  • Quality tested – each lot evaluated by SDS-PAGE and Western blotting


Proteins (0.1 to 0.2mg/mL of each) in 62.5mM Tris-HCl (pH 7.0 at 25°C), 1mM EDTA, 2% SDS, 50mM DTT, 30mM NaCl, 1mM NaN3, 0.01% bromophenol blue and 50% glycerol; Component proteins: beta-galactosidase (116kDa), bovine serum albumin (66.2kDa), ovalbumin (45.0kDa), lactate dehydrogenase (35.0kDa), REase Bsp98I (25.0kDa), beta-lactoglobulin (18.4kDa), lysozyme (14.4kDa)
