Thermo Scientific™ PageRuler™ Prestained NIR Protein Ladder
Description
The Thermo Scientific™ PageRuler Prestained NIR Protein Ladder is a mixture of 10 proteins (11 to 250KDa) that are blue-stained and fluor-labeled for near-IR fluorescent visualization and protein sizing following electrophoresis.
The protein MW markers in this ladder resolve into sharp bands when analyzed by SDS-PAGE and are labeled with a fluorescent dye for visualization with instruments equipped for detection of near-infrared (NIR) fluorescence. The bands are also directly visible because the proteins are prestained blue. The 55kDa band is of greater intensity and serves as a reference band. The protein ladder is conveniently packaged and ready to use: no heating, dilution or addition of a reducing agent is required before use.
Highlights:
- Size range 10 proteins spanning 11 to 250kDa
- Fluorescent detect using 670nm red laser or 700nm channels with fluorescence imagers
- Ready-to-use supplied in a loading buffer for direct loading on gels
- Sharp bands excellent sizing for near-infrared visualization of protein gels and blots
- Reference band 55kDa band has greater intensity for easy orientation
- Quality tested each lot evaluated by SDS-PAGE and Western blotting
