Pierce Unstained Protein Molecular Weight Marker


Unstained MW marker composed of native proteins with precise molecular weights.

 
Pierce Unstained Protein Molecular Weight Marker.

Thermo Scientific Unstained Protein Molecular Weight Marker is a mixture of seven (7) native proteins (14.4kDa to 116kDa) for use as size standards in protein electrophoresis (SDS-PAGE).

This 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.

Highlights:

  • 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

Includes:

  • Proteins (0.1-0.2mg/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)

Applications:

  • Accurate protein sizing on SDS-polyacrylamide gels and Western blots.
