Thermo Scientific™ PageRuler™ Prestained NIR Protein Ladder

Thermo Scientific™ PageRuler™ Prestained NIR Protein Ladder

Thermo Scientific PageRuler Prestained NIR Protein Ladder is a mixture of 10 proteins (11 to 250 kDa) that are blue-stained and fluor-labeled for near-IR fluorescent visualization and protein sizing following electrophoresis. The protein ladder is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.

Features

• Fluorescent—detect using 670 nm red laser or 700 nm channels with fluorescence imagers
• Reference band—55 kDa band has greater intensity for easy orientation

Contents

• Two vials of 250 µL each
• Storage buffer: 62.5 mM Tris-H3PO4 (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3 and 33% glycerol
