Description

Description

The Thermo Scientific™ PageRuler Unstained High Range Protein Ladder is a mixture of 8 unstained proteins (60 to 250kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.

The protein MW markers in this ladder resolve into clearly identifiable, sharp bands when analyzed by SDS-PAGE and stained with coomassie dye or silver. The 150kDa band is of greater intensity and serves as a reference band. Proteins can be detected on Western blots by staining with Ponceau S, coomassie blue or other protein stains. In addition, the ladder proteins contain an integral Step-tag™ II Sequence and may be detected on Western blots using Strep-Tactin™ Conjugates. The PageRuler Unstained High Range Protein Ladder is supplied ready-to-use: no heating, dilution or addition of a reducing agent is required before use.

Highlights:

  • Size range 8 proteins spanning 60 to 250kDa

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

  • Sharp bands excellent accuracy for detection with coomassie or silver stains

  • Reference band 150kDa band has greater intensity for easy orientation

  • Tagged each protein in the ladder contains an integral Strep-tag™ II Sequence

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

Includes:

Proteins (0.02 to 0.05mg/mL of each) in 62.5mM Tris-H3PO4 (pH 7.5 at 25°C), 1mM EDTA, 2% SDS, 100mM DTT, 1mM NaN3, 0.01% bromophenol blue and 33% glycerol

Recommended for:

Accurate protein sizing on SDS-polyacrylamide gels and Western blots
