PageRuler Prestained NIR Protein Ladder

A broad-range MW marker for near-infrared (IR) fluorescence applications

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
