Brand:  Thermo Scientific™ 26637

Product Code. 12201702

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
