Thermo Scientific™ PageRuler™ Unstained High Range Protein Ladder
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
